Welcome to the nonprofit show and welcome to 2024. We are really glad you're here with us on this journey. Today, Julia Patrick, CEO of the American Nonprofit Academy, she's in the hot seat. I get to interview Julia and she is here to talk to us about connecting with leaders and all about making a new resolution to do this kind of work. So lots of good things to share with us. Julia, lovely new headshot by the way. Thank you.  And so I had to get new headshots, not an easy thing because I'm a vain woman. I'm just putting it in. It's been great through our four years on this and we're past 950 episodes. And if any of you go back and watch, you will see the transformation of our hair and our makeup and our glasses. Anyway, I'm Jarrett Ransom, nonprofit nerd CEO of the Raven Group, honored to be here with you Julia, CEO of the American Nonprofit Academy. Also extremely honored. And Julia, I'm gonna let you actually share a little bit about our presenting sponsors. You know, it's really fun. Most of these folks have been with us from the very beginning, but this year we've added two new sponsors and we're really excited. But our new sponsors are 180 Management Group and JMT Consulting, which we're gonna talk more about later. But also we are partnered day in and day out with amazing, amazing support from Bloomerang, American Nonprofit Academy, Nonprofit Thought Leader, Staffing Boutique, Your Part-Time Controller, Fundraising Academy at National University, Nonprofit Nerd and Nonprofit Tech Tuck. Jarrett, these are the folks that are like the gas to our engines, right? Yeah, absolutely. And they've helped us to produce nearly 1,000. Yeah, that's right, 1,000. I'm like, that's such a hard number to say, but you can find us, actually go ahead and pull out your phone. You can scan that QR code right now. You can still find us on broadcast and podcast. And you will find all of our previous episodes from our guests, including these master classes that we just referred to. And today is one of those. So Julia C. Patrick, CEO of the American Nonprofit Academy. Welcome to the hot seat.  You know, and I pull up everything. And then I'm like, holy cow, it's me. I'm like, wow, okay, I got to sharpen up.  And so I want to be sharp. I'm bringing all the curveballs because I know how much Julia, you like them. So let's dive in, talk to us about leaders, leadership and really you're going to kick us off here with why should we connect with leaders? What is that? What are you talking about in this space? So this today, this master class, which we've talked about these concepts, you know, over time, this really emanated from something that was absolutely fascinating late in last fall. I was very, very honored to be a part of a very prestigious situation where I got to interview other nonprofit CEOs from my community that were in line for a major, major award, I mean, significant, like transformational for their career, right? And so I was with four other judges, amazing people. I looked around that table and I was like, wow, why am I here? Cause these people are rock stars. But once I got past that and we started interviewing people over a three day period, I realized that there was a disconnect between all these leaders and we all thought we knew what everyone did. But you know what, Jared? We didn't, there were a lot of holes and these are venerable organizations, well sought after leaders, leaders who are in the public eye, right? People that we all knew. And this was what my lesson was. We thought we knew them, but we really didn't. And so it really bubbled up something inside of my mind that said, you know, with this pandemic and how we pulled back, we haven't had those cocktail moments where we're like, hey, did you hear about this new thing I'm doing? Or we haven't met up at different things, right? So we've probably for the most part done a poor job about telling everybody what we're doing, what we've let go, what we've taken on, just what we're doing. That's a big one. I love that you said like, we haven't had those cocktail moments as often as frequent as we were having them. You know, I'm guilty of this too, Julia, of, oh yeah, I've met so and so, we've known each other for 10, 15, 20 years, right? And I just assume that what they're doing is the same thing they did 10, 15, 20 years ago. But I know that to be false because as I've served as interim CEO, right? And in other positions, I have sunset it programs, I have launched new programs.  And so connecting with these leaders, do you recommend, here's a curveball, do you recommend that there's like, like how do we get these leaders together? Or should we be doing it one-on-one? You know, Jared, that's a great question. And I think there's that old fashioned line that says preach to the choir.  And we kind of forget that there's a heck of a lot of things going out there. Let's go back to that number, 1.8 million registered nonprofits in our country. And most of our nonprofits have many things that they do. They might have started out as a food pantry, but now they're a domestic, they have domestic violence shelter services, or maybe they have after-school learning or they have college scholarship programs, whatever, right? And so we have to do a better job about sharing our story with our community. And you know what, Jared, to me, I think we're super focused on just sharing our stories toward donors. Well, and I was gonna ask you, and are we also super focused on, we sent an email on that, or we put it on our website. So check, check, we're done. Like, it doesn't sound like that's enough. No, no.  I get about 250 to 275 on heavy day 300. And these are not all like, you know, come shop the sale at X, Y, Z boutique. These are like nonprofits who, you know, who want to communicate with our team and us that have important things to say just like you, right? I mean, you've got to be in that same ballpark. There's only so much time and so much bandwidth that I have to recognize what I'm seeing, what I'm reading, what I'm scanning, and then apply those connections, right? And that's connection. The connection is big. So who is it we want to connect with, right? Like, who is on this leadership list? Right, and this is the thing. You got to step back, step back. And you've got to say, they need to be people who can influence, impact, connect and collaborate. Okay, so four things. Influence, impact, connect and collaborate. Because you don't know where somebody might be like, oh, holy moly, our nonprofit doesn't do that, but I know a nonprofit who does, right? That can lead you to business or can lead you to grants or can lead you to awards or contracts, right? Or maybe you just do a joint venture, right? You just don't know. But again, if we don't really know what we're doing as well as we should, that's where this falls down. The other piece of this, Jared, that I really think is important is that I think in the nonprofit sector, there are very few organizations within our sector or types within the sector that do a good job of policy and advocacy work. And so I think that these are people who can influence outcome. It's not just about money. And so we have, you just pulled up the slide, we have a lot of different types of people. We have our section leaders. We have just nonprofit leaders, whether we think we're gonna work with them or not or that we have some viability, doesn't matter. Government leaders, every time there is a change in government, you need to have those people on your database. So for example, governors offices will have heads of departments that impact your nonprofit, right? How many of our nonprofits don't even know who those folks are? Absolutely. Until we need them or we read about them or they're leaving office, right? We gotta get on this. Community leaders, this is everybody that you might read about online or in your paper, you might see those folks that are community champions. Media leaders, this is the other thing I think a lot of times in the nonprofit sector we're afraid of getting these people on our databases and communicating with them until we're asked and I'm advising, don't ask. I mean, you need to push out. Don't wait for them to come to you. Don't be afraid of the media. And then board of director leaders, I mean, this is another thing we miss out. Looking at your, if you did nothing, nothing, but do the top 10 to top 25 nonprofits in your community, whether they're in your sector or not, even if you just did it by budget and you've got the board members, board chairs on your database, magic.  And then, and I'm gonna interject, I've seen board members and we know this, right? If you serve on one board, typically you're serving on another and maybe even multiples, right? Those board members, they are advocates, right? And they're really doing their work in the community. They could be the collaborative person. They could be the one that says, you know what? I just heard from X, Y, and Z organization. I feel like there's some synergies here. Might we consider a conversation? It's so true, Jared. Or we've talked about this with our friends from fundraising academy. And that is like, sometimes you have a donor that comes to you and they want to do something specific, but it's not really a good fit for your organization, right? Okay. What if you said, well, we don't really do this, but this nonprofit over here does. That's free money. That's magic, right? And so I think we've got to be like, less focused in on ourselves and really looking out and saying, what is the ecosystem in our community, in our region of nonprofits, right? And leadership. The other thing that I think is really, really important before we move on, that is we're not putting enough emphasis on school leaders. And I'm saying everything from, depending on how your community does of your state, you know, if you have board or governance agent officials, if you have districts, everything from like the community college presidents, the university presidents, private public institutions, because guess what? These people are educating our future leaders, right? And so if we're communicating about what it is we are seeing or what we're needing or what we're doing, that's gonna be a filter down at best. That to me is a big a-ha, Julia, because I would have only thought of like the school board, you know, like we only wanna do the town city school board not, you know, if we have a community college or if we have a university in our community, what that looks like. So that's fascinating to me to really think broader. Yeah, yeah, because you know, Jared, I think one of the things is that if we're only building what we believe is the impact and connectivity for our own organizations, we're not really gonna move ahead. When we have somebody else deliver a new concept, a new partnership, a new donor, a new advocate, that's when the magic is happening, because we can only do so much ourselves, right? Right, right. And so we wanna kinda start to support and propel this notion of building community support. And that comes to me right directly from leaders. Well, and it makes me think it takes a village. In a lot of ways, it takes a village. But really, you know, nonprofits are here to serve as a solution to a community problem. You've got a couple of more here that I want us to spend some time on before we move forward. So religious faith leaders as well as funding leaders, talk to us about these two categories. So I think in my lifetime, you know, when I was a little girl, we really included religious and faith leaders. I think that was a big part of what we do. And then we've kind of had this more attention to separation of church and state, and we've really tried to, you know, move that apart. And I'm revisiting that mentally, my own self, and saying, look, you know, we don't need to agree or buy in to another faith, but we need to agree and buy in to community support, right? So no matter what that faith construct is, you need to be allowing those voices that are on the front lines of many topics to join you because it's not just, you know, the Methodists are gonna support Methodist organizations and the Catholics are gonna support Catholic organizations.  And we know this, we know this, Jared, from the Giving USA data that keeps showing how Americans are changing their donations to faith-oriented groups, right? So I feel like that's an ecosystem where we can garner a lot of support and we might learn something, right? We might learn something. I've gotta say, you know, I was really shocked. I was leading a strategic planning board meeting and there was, from this community, there was like, you know, someone from the fire team, someone from the police department, there was a faith leader, there was a school district, like they really had like, check, check, check your boxes. But what I was fascinated by this faith leader mentioned in strategic planning, they never expected to be a part of the opioid pandemic or epidemic, which is a crisis, we'll call it a crisis, right? It's both to wear his congregation, like they at their church had, you know, Narcan, they had solutions, right, to the community problem, because that's where the community was coming, whether it was a parent, a grandparent, and to be a part and to witness this conversation, it's like all coming together for me now, Julia, because I swore to them I was in a Hallmark movie. I was like, where is the camera? Because these, like these are all of the main big players of the town, and it's a small town. And you know, Jared, I love that you talked about that because if you can step aside from the faith construct, you know, and we're gonna have Muji Qawajir coming on next week talking about raising money and stewarding the money for a Muslim community foundation, right? I mean, talk about, that's a brave thing for us to do, I think, given in the war in the Middle East, you know, these are the things that we need to kind of break down and look at and say, okay, this is a humanity issue, right? And so no matter what the faith construct is, these are the people like your church, they're on the front lines. Doesn't matter if they're Episcopalian or they're Lutheran, right?  And you know, Jared, we don't do that enough.  Yeah, I see us really in a silo and this list, I'm gonna pull it up again because it is a fascinating list. You know, pulling together these thought leaders, again, what I'm hearing you say, and again, this aha moment is we stay in our lane too much and maybe it becomes comfortable because of everything that's on our plate and all the responsibilities and our busy schedules and calendars. But when we come together and we keep a finger of the pulse of what is happening in all corners of our community with these leaders, again, because for everyone watching and listening, these are the leaders that should be on that leadership list. So start thinking about this, take a screenshot of this, right? Pull out your phone, whatever you need to do there. It's just fascinating. What about the delivery and the maintenance? So now we know who needs to be on the list, right? Like how do we deliver communications? How do we maintain this leadership list? Who is communicating and who owns the list? Right, so most nonprofits in our country only have donor lists. Let's be honest, right? They look at a prospect or an existing donor and they're like, that's who goes in the database. And we fill the database with even their dog Fluffy's name, right? Their favorite poodle's name, right? I mean, you're not wrong, that is, I'm not correct. No, I mean, hey, listen, I've sat in those board meetings where they deliver the lists and say, okay, who do you know? Or what's the poodle's missing name, right? I mean, yeah, I know that this goes on and that's great. But what I'm saying is that don't overburden yourself with the concept of starting a whole nother database because for a lot of people, this is an arduous process that just seems daunting. My recommendation is to do something as simple as a very, very basic spreadsheet where you get the person's name, where they're from. You can use those symbols that we created to align them to what part of the sector and their email address. And then start sending them information. It might be a press release, it might be a newsletter, it doesn't have to hammer on donations, but it needs to hammer on impact. What we're doing, what we're looking for, where we're gonna be, these are the awards we won. This is the collaboration we're looking for. They don't have to be novels, they don't have to be huge tomes that are too hard to get through. They can be a very simple branded headline and then some points, right? Julia, sorry, I'm interrupting. Besides information, is there a call to action? Are we doing an open call to action, reach out to us? Would love to schedule a call, better yet, would love to do a tour. I was gonna say tour. Okay. Yeah, I was gonna say tour and what I think with this leadership list you could do is you could do tour with a CEO. Because remember who you're sending this to and you can see like, do you want a tour with the CEO or let's have a round table or let's have a brown bag lunch or we're gonna offer donuts and coffee and we're gonna talk about this topic or whatever. I mean, it really goes as far as you want to and how you wanna engage. I mean, I know that there are many communities that have CEO forums and mastermind groups. And I mean, this is the sort of thing that you can engage in and build some camaraderie, opportunities to do things that you might not have ever even dreamt of, right? That somebody else can bring to you. No, I think it's fascinating, and I'm a little overwhelmed if I'm being honest because here in our community, we have 33,000 registered nonprofits. How in the heck, Julia Patrick? Do we stay in touch with all 33,000? Do you recommend that we stay kind of mission aligned or is it we're casting the net far and wide and we wanna include, for that example, all 33,000 because you just never know what might come about. Right, so the reality is in our community and I'm gonna push back a little bit on you is that when you go in our community, in our state to the Secretary of State, you see over 45,000 registered and there's a something that's tracked every day. Now, some of these people, they're formed at their kitchen table and they're not a go and just see necessarily. But the reality is for most folks, they're gonna have tens of thousands. So you wanna start with the people that impact your organization first, right? Your sector, things of that nature, people that you are already working with, collaborating with who know you or should know you. So if it's education, we wanna focus on kind of like the educational organizations. If it's homelessness, hunger, we wanna focus on the similar, okay. So you wanna start there. And then you want to set some limits and some measurements. And so this is what I think is a fabulous thing to do with volunteers because this can be done at home. This can be somebody that might be, you know, their abilities challenged. They're not gonna be able to go out and dig holes in on your property, right? But this is the thing, Jarrett. For me, I think you need to say, this is our baseline number. And if you started, great, you'll have a baseline number. If you haven't, you can say within the first two quarters of 2024, we wanna have 100 contacts. That's fantastic. We wanna have 500, whatever that number is, make it realistic. And I can imagine you wanna ask the team, right? Like your colleagues or C-suite others, you know, programmers to provide contacts for that list as well as your board members. Like who else should be on this list, right? Exactly. And I think the thing of it is, Jarrett, and we said this at the very beginning, you need to start with this is not for asking money. This is for asking influence and connectivity. So not just who has the deep pockets, because that's what we all do. That's what we all think about, right? And that's not where this goes because it will build your business faster than you ever dreamt. Well, you are knocking my socks off because I know we have talked about leadership list in the past, you know, contacting these leaders regularly, but there is just so much to think about. And as we kick off the new year, right, Julia, like there's so much goodness when it comes to this. So I hope everyone watching and listening is really taking advantage of building this list, getting the information from you. This is why we turn the tables on each other, my friend, because you've been in the sector for a long time. I've been in the sector a long time. We are, I feel so, I'll speak for myself. I feel so blessed and honored to be able to talk to leaders from around the globe. And yet here we are with so much of our own lived experience. We don't get to share often when we have another guest on. So we might be doing a little more of this in 2024. So if this is something that you enjoy or there's a topic that you know we've talked about before and you want us to dig deeper. I know Julia Patrick, CEO of the American Nonprofit Academy, would love to hear from you. Do check out the American Nonprofit Academy website. Julia, tell us, because I know a lot of people come to us for the show, but your website has an enormous amount of resources on there. It does. I mean, we house the shows and connectivity to the shows. We have a lot of information. We have worksheets. Yeah, it's a lot. And we're here to support our industry and this is something that my team and I share a passion for and so yeah, absolutely. It's fantastic. Thank you. Well, Julia Patrick, thank you, my friend and my co-host to be here today in the hot seat. Julia Patrick, CEO of the American Nonprofit Academy and I'm Jarrett Ransom, nonprofit married CEO of the Raven Group where I just got to turn the table on Julia. And I ask you again, Julia, if you wanna honor our sponsors and take us off for today. I do. Thank you so much for, you know, I marvel at what you do. I love your energy every day. And you and I, when the few times that we get to get, we're together, IRL in real life, I love your energy and we always have so much to talk about. So this has been really a lot of fun. So I say- And it goes fast. It goes really fast. And I also say thank you to our amazing sponsors and partners, Blumerang American Nonprofit Academy, Nonprofit Thought Leaders, Staffing Boutique, your part-time controller, 180 Management Group, Fundraising Academy at National University, JMT Consulting, Nonprofit Nerd and Nonprofit Tech Talk. These are the folks literally that are with us day in and day out, moving through the end of our third year, moving into our fourth year, nearly 1,000 shows. So it's an amazing thing. But more importantly, you know, Jarrett and I came up with this little mantra at the very beginning and it means something new and different every day I say it, which is super kooky, but it's really true. And it goes like this, to stay well, so you can do well. Thanks, Jarrett.


Hi there and welcome to the short video, having looked at the account module in a little bit more detail. As you can see there, you've got the product name, you've got the fact that you've bought or sold, your stake size, your average price that you got into your position, your real-time profit and loss, and details of any risk management that you have right there. You can also open up a sale or a buy order ticket by simply left-clicking on the price as per usual. From here as well, you can also expand your position out slightly to get the entire order number, or if you've got an aggregate position as we do right here, if I just minimize that for a second, I've got two trades running right there, and if I expand that out, I can see the two child orders right here. This top section here is the aggregate, and then this is the two child orders. Now I can actually choose to close out of my trade by clicking on the little red X right here. I can choose to do the aggregate right here, or do one trade at a time. So for example, I want to close out this trade, simply left-click there, then click confirm, and that trade's been done, and conversely, if I want to close out the entire aggregate position, you click on the aggregate row, click the same button, click confirm, and that has been done. It really is as simple as that. You notice there that on my gold position right now, I don't have any stop loss or take profit added. All you could do is click on the modify bet button right here, and it'll allow me to, I can close it at my position here if I want to, gives me all the details of my trade right here. I can pop these sections up right here, add a stop loss and take profit. For example, if I want to have a stop loss set at 300, and a take profit set at 900, all I have to do is do it like so, and then click modify. As you can see there, that's been updated there on my account module, no problem at all. So my next section I'm going to quickly show you is going to be my pending orders blotter. Now from here, I've got three pending orders, one in gold, silver, and US 30. I've got a selection of stop entries to buy and stop entries to sell. You've got your stake size, you've got your expiry, which is GTC in this instance. I've got the trigger price right here. In fact, in two of my orders right now, I've got boundary set as well, and I've also got the details of any risk management. Again, if I want to cancel any of those, just click on the X button and then confirm. Or if I want to go ahead and modify any of these trades, just click the modify button, I can go ahead and address management as simple as that. The last bit I want to quickly show you is the history tab. The history tab is actually quite useful. It obviously gives you details of all your transactions on your account, be it opening trades, closing trades, stop losses being hit, take profits being hit, pending orders being executed, overnight financing, anything like that. So there can be quite a huge amount of detail on here. From here, you've actually got a little calendar function. So if you want to get, if you want to be quite specific about the time area right here, simple enough to select from here. And you can also sort any of these sections. Any section there or column I should say, with any arrows attached to it, you can sort as simple as that. Okay. And it's also worth noting that you've got this little information button right here. By left clicking here, it gives you more of a detailed view behind each transaction that you've done, be it executing a trade or just your overnight financing. You've got all the time stamps and order IDs, anything else on here as well. And you can also see the price depth ladder to see exactly where you got executed. And I just scroll down here, you can see a wide selection of different types. If, for example, you want to see some of your holding costs, for example, all you have to do is simply left click here, and you can see your holding costs right here. And then left clicking on the view additional information will give you a full breakdown of all your overnight financing costs by product and the actual totals right here on the right hand side. And that is pretty much the main aspects there of the account module. But if I actually go up to account right here, you can break these sections out separately. Okay, so you don't necessarily just have to utilize these areas right here. And there's actually one final piece, which is the execution blotter. Now, what the execution blotter does is allows you to see any of your trades that were open or closed, plus any profit or loss that was attached to that. Sometimes I quite like to look at this just to get a bit of a flavor of how many trades have gone right and how many trades have gone wrong, and kind of a breakdown of the profit and loss. And it strips out a lot of a lot of the other noise that you do get on the history tab.


Welcome to today's lecture, this is on design analysis of gear pumps part 2, this is continuation of part 1. Now, last time what we have learned that in gear pumps external to the gear pump, if we consider the blue one is the driving one, then the flow is in here and then that is carried out to the other side of the pump and there must be the volume expansion and volume compression in this zone. Actually, we would say it can be shown that the volume displaced among three contacts, one contact with this wall, one contact with this wall and then contact between tooth. That space is will be in compressive here and this will be in expansion mode here. That is two contacts of two gears and casing and meshing teeth at center at both inlet and outlet. And the volume displacement is exactly equal to the summation of active amount of trapped volume. The active amount means if we look into this some oil is going back to the other side. So, active amount is the what is the volume displacement happening here. Now, also we learned that if we consider this is the external pump, in that case what we have to consider? We have to consider a control volume which is which constituted by the point here, the point at the mesh and the point on the other side of the wall. Now, what is happening when this is rotating in the clockwise rotation, then this is rotating in the anticlockwise directions. This point is going downwards, whether these two points are coming closer. We have to consider the contact point. I mean when this just left this wall from that point to the situation when this point again will leave this wall. So, in that way we can it can be shown that this area that is varying and this area varying in a nature that gradually this area is being compressed. So, that can be derived or that can be written in the equation form by considering a small amount of going in here and going in here and going out from this zone here. Now, this is for d theta 1 rotation of the drive gear. So, we can write down this equation in this form and then the final equation for the theoretical flow rate of the gear pump is in dimensionless form is obtained say Qd is equal to half into Ra 1, Ra 1 which is the addendum or tip circle radius of this gear drive gear. Rho 1 is the instantaneous radius at the contact point, Rp 1 by Rp 2 is equal to the ratio of this pitch circle radius of these two gears which is normally is 1 and rho 2 is the contact distance here. So, if we would like to equate in this way what we have to calculate each and every instant we have to calculate these two rho 1 and rho 2 because other dimension are fixed. So, if these two are varying naturally this dimensionless flow is also varying. We have to keep in mind this derivation is actually derivation of this area into the thickness of the pump which is constant. And we have also learnt in the dimensionless form what we did to make this flow is dimensionless form. We divided this into the Rb square and the width as well as divided by the speed to get this flow rate dimensionless flow rate. Now, to determine this rho 1 and rho 2, first of all we should analyze the gear mesh geometry with varying theta, theta is varying the shaft rotational angle which is shaft rotational angle and the instantaneous length of action and thereby the instantaneous flow rate is further determined as before that I would say that while we are doing some geometric analysis, first of all we must know what are the axis system we have considered. In this case if we consider capital X and Y this is fixed to the reference frame that is this is a fixed axis which as you can see this is X and Y capital X and capital Y and again that we should say that this it is ordinated by fixed angle with the line joining the centers of the gears. This is the center of line joining the centers of the gears from here this at this angle. Now, we must know what is this angle then we have considered another axis system XY which is fixed to the this gear the driving gear. Now, it is like that that XY small XY axis is through the middle of this one teeth which with which just the contact has started you see this is rotating in the clockwise directions. So, this is in the anticlockwise direction the contact has just started here at that position if we consider the half of this teeth then we get this line which is small X axis. Now, when theta is equal to 0 then this XY axis small XY axis coincide with capital XY axis that means by knowing this axis position with knowing the number of teeth etcetera, then we can find out what will be the capital XY axis we have considered. This is not a difficult task we can assign that and then what we do we consider this geometry we are trying to calculate row 1 and row 2 and then we consider this point is moving gradually and then we find out this length doing this pressure angle and from there we find out this length row 1 and row 2. Ultimately we find out the length of contact and ultimately we express the flow equations in terms of length of contact it is written here how this X axis are considered when theta 1 is equal to 0. Now, ultimately we can replace this row 1 and row 2 and the equation is expressed in terms of length of contact instantaneous length of contact which is the contact from the pitch point to the instantaneous contact we have to consider this length. If we can calculate this length then this will be expressed easily because other terms are constant. Now, what is instantaneous point of tooth contact that if we define that in terms of this contact radius and angle then contact radius is expressed in this form you can check this geometry and you will find that this is the expression and then we consider this beta 1 angle which was last time shown this can be derived this beta 1 angle in this form and then finally with psi 1 is equal to pi by 2 z minus 1 that is this angle is equal to nothing but half of this angle half of this this is pi by z 1 is equal to tooth thickness basically I mean half one tooth angle and half of that ok. So, possibly this angle psi 1 is defined here no not defined but just consider this angle is calculated from the relation of the teeth number only. Then equation 12 and 13 must be solved numerically for a given theta 1 now we shall consider at starting this equation the rho 1 at starting will be expressed in this form and then contact length L s in dimension less form is also expressed as like this then we get this angle expressed by this expression where this is also at the starting and then the instantaneous length of tooth contact is defined as L is equal to rho 1 sin of this angle and say alpha. Now, the relationship between rho 1 and beta 1 is non-linear hence the numerical solution to this equation will yield the most accurate results for instantaneous length of action we can solve this numerically but what I would like to mention say this alpha alpha is the pressure angle now we have to take care of this alpha say here we consider that might be with generated by a standard pressure angle say 20 degree pressure angle then when they are meshing at if they mesh at their standard pitch circle radius then alpha remain constant that is working pressure angle remain same as 20 degree but if we change the centre distance definitely this working pressure angle will change. Now we should keep in mind sometimes the teeth number are taken less than the allowable teeth number to avoid the undercut and in that case working pressure angle changes. Therefore, we should always keep in mind this pressure angle is equal to the working pressure angle not the standard pressure angle. While we are trying to find out the base circle radius of such gear then we consider only the standard pressure angle there. So, we should not confuse with the working pressure angle and the standard pressure angle all such expression we have to consider the working pressure angle. However, a closed from approximation this I told that we can we should go for the numerical analysis I mean numerical solutions to find out the flow but recently wandering and his co-author is Kasar Gadha they have proposed a closed from solution. So, now to arrived into such closed from solutions first of all we have to consider all contacts point but before that I would like to mention in a methods which we have discussed so far what we have done we have considered a control volume and we have a control volume for that what we observe that basically the area is changing and the width remain constant. So, if we can repeat the change of area variation of area with theta then we can find out the flow variations. However, there is another method in which what is done we consider that those three points definitely but instead of considering this area what we consider we consider a beam joining this instantaneous tooth contact point and the point where this tooth is just separating the exposed zone to the trapped zone. Now, if I consider that as a beam say this point is point of contact may be here the casing is or my might be here anyway if you take these two point what we can consider this is we can consider a beam with uniform load which is equal to the pressure the load is equal to the pressure into may be the area that is uniform load by that way we can find out that how much resultant load acting on this line at the midpoint and we will find that from that midpoint we have a distance to the centre of the gate. So, therefore, if we multiply that distance into this load we will find a torque. So, that torque is acting on this gear similarly if we consider the other gear also we will find another torque which is acting on the other gear. Now, this total torque is transmitted by the shaft. So, in that way we can calculate what is the total power or total energy that definitely that is a rotational angle into that torque if you consider the power the rate of I mean speed in that case we have to consider speed and the torque. Now, this equation we are considering the energy not the power energy in that case what we consider that m 1 is the torque here instantaneous into the angle of rotation d theta 1 and m 2 is on the other gear and multiplied by d theta 2. So, this is the total energy. Now, again this energy can be expressed in form of the rate of change of volume and the pressure. Now, this pressure is the differential pressure that mean output pressure minus the input pressure in this case we consider the input pressure is 0. So, we have considered the output pressure here. Now, if we consider these two equations then we can easily calculate because the same pressure we are considering for this two. So, we can easily calculate rate of change of volume with the angle of rotation and from there again considering this change of this length that mean change in torque with of course, constant pressure because geometrically as the volume is being displaced here there is a compression in this side expansion then definitely this length is also changing accordingly. So, we have to find this length instantaneous length to find out the instantaneous torque. Now, again we have to consider the geometric through this geometric analysis we arrived into this equation with this energy method right. Then if we compare with this equation earlier which we have derived considering the control volume this equation more or less same only what we find that here the half is not there and here the instantaneous square of the instantaneous length where this is some value of this u. Now, we can relate this u with lay L with this relations while this was derived. In fact, this can be also derived within this form but here the geometric analysis was different from this axis considerations. So, in that way the formula is coming like but what is found that these are basically same or in other words now if we would like to find out the numerical solutions for the flow then whether we use this equation or use this equation we will arrived into same result. However, to for the close from solution we consider this equation 10 and we are trying to find out whether this can be solved. Now, close from solution means you have to find out you have to relate this L with theta with some approximation or with some solution. Now, let us say that what the monitoring at all have done for generating a closed from solution for the instantaneous pump flow a Taylor series expansion is done. In that case L which we have expressed in this form for very small value of theta I mean we have to consider in this case for such equations that theta 1 varying very discretely with a small amount. Then in Taylor series expansion we can express this instantaneous length of contact is in this form where the rho 1 s is the initial rho 1 that is at the starting s means at the starting point and as well because this angle is fixed it is not varying whether beta 1 is varying this beta 1 is varying as this gear rotates and theta 1 for which we are calculating the this one it is small we have considered and then this is the working pressure angle. So, we can express in this form obviously the other terms there is Taylor series mean there are other terms also which is negligibly small and we have neglected those. So, this simply expressed in this form. L is then express L s minus rho 1 s cos alpha beta 1 s that if you look into this L then L s minus when it is just moved we can calculate this part and L is expressed in this form. Then this of course could be considered, but again further approximation is done that this rho 1 s cos psi minus beta 1 s into say alpha is equal to 1. Why this is considered this from the geometry it can be proved this is very close to 1. We can say that this equation 80 18 is now reduced to this one and we may consider that there is some error which error can be found out by subtracting 19 from 18 and then it is found that at theta 1 is equal to 0 you can see that it is 0 error is 0, but it will increase slightly with the increase in theta 1, but remember this theta 1 we are considering what will be what should be the maximum theta 1 theta 1 is equal to 0 then what will be the maximum theta 1 just 1 pitch rotation 1 pitch rotations is means that 2 pi or actually not even 1 pitch 1 base pitch you can say and for that the total rotation is equal to 2 pi by z 2 pi by z and z is usually taken may be 20 at the lowest may be 10 not less than that at least I have not seen I do not know whether it can be 10, but you usually will find it in the range of 20. So, now you can find out 360 divided by 20 is 18 degree and you can examine that for 18 degree when theta 1 is 18 degree if you calculate these angles you will find that this error is not 0 slightly more, but still it is it will be within acceptable limit. However, if we with this closed solution if we plot the graph for flow ripple then we can only examine how much difference will be there. Now, the again if we use this general form of equations this L we have to express what we have derived and the maximum flow now we are trying to find out when the maximum flow will occur. If we examine this equation then when L is equal to 0 then there will be the maximum flow. Now, this maximum flow simply if we put this 0 this is expressed by q d max and we find in equation 10 this simply this term is not there. Now, again one interesting point I would like to mention that R p 1 by R p 2 usually you will find 1 that means they are of same size here, but in some design they are not equal. However, this number is not very big and what we will find this is close to 1 either it will be less than 1 or it will be higher than 1, but it is very close to 1 that means this term is always close to 2. Similarly, the minimum flow output of pump occurs when L is maximum that means when it is at the starting because we have in this geometry we have considered that from this starting point it is gradually approaching to this point and our total length is definitely at starting and then final length, but this length will gradually decrease and however this length will be maximum when it is L s and substituting that what we find that this will be the minimum flow. And this negative sign with this as a maximum value the total value will be minimum. Therefore, what we can find in repose a maximum peak amplitude from lowest point to the highest point definitely q d max by q d min which is again expressed by this one and this can be easily calculated because this L s will be fixed geometrically we can find out L s we do not have to go for any numerical solutions in this case. Now, if we would like to find out the average flow then we have to equate all such flow from starting point to the end point that means we can make this integral. Now here just keep in mind that here minus sign has been used because this minus sign is in the opposite from this pitch point actually this total length will be added that means we have to consider from the starting to the end point and which is which must be equal to what this is equal to the base pitch simply we can write here this is the base pitch length here. Now then this integration becomes like this where we have introduced a new term M which is expressed in this form in that case again we have to calculate L s and L f you can see this L s plus L f that is actually total length we are considering the actually total length. So, this is while you are equating you have to be a little careful about this plus minus sign. Now usually the teeth numbers of driver and driven gear are same in common gear pumps. However, pumps with equal as well as different numbers of gear teeth are considered for the purpose of comparing and finding the optimum flow ripple characteristics. Now this exercise is done by Malring to find out whether is there any advantage to optimize the flow ripple by changing the gear ratio from 1. Now to make a clear comparison among pumps of different teeth pairs the average flow rate of each pump is maintained constant in the design process. Now the advantage of dimension less analysis is that we can find out the non-dimensional flow and then we can multiply with actual dimension to get the flow or in other words depending on the flow rate what we done suppose we select the teeth numbers. We select then the speed of whatever it might be or centre distance working pressure angle all we fix up. So, we can equate for non-dimensional flow. Now then if you would like to have more flow from this pump simply what you can do one is of obviously you can flow rate if you want more flow rate one is that you can go on increasing the speed, but otherwise for a fixed speed what we can do we can simply change the module we can simply change the size to have more volume output. So, this means that depending on the flow rate usually say speed depending on the accuracy of this pump manufacturing accuracy of this pump there is a speed limitation say for example in usually gear pump you may not find more than 2500 rpm. If you go for very high speed then there will be very high frequency noise will be there. Again of course that how it is the teeth are ground all such things depends on what is the casing dimensions how is the error in centre distance all such things will depend to have the flow. So, then depending on that depending on the purpose what we do we finalize that what will be the speed then if we want to increase the flow rate with that speed maximum flow rate what we do we go for higher module instead of 4 module we can go for 5 module like this. Now in other words q d average as expressed in equation 24 is held constant for all pump designs. So, here I shall show you some results or typical results of such analysis in that case we have considered this is fixed. Now what we have considered the result of flows form approximation we have considered to find out the solution that is we have considered l is equal to l s minus theta 1 this expression from the approximation we have found and then substituting this we get the starting length of action l s is defined in equation 15 the final length l f is derived as derived in equation 17 and then with this we get l f is equal to is expressed like this. Now this separately we have to calculate now theta 1 starting and theta 1 final that you can say as I told that is simply 2 pi divided by number of teeth of the driving gear which we are driving or gear 1 we would say. So, this calculation will not be difficult and we know this formula and from there we can calculate we can calculate the final length of contact means this one where this expression for the final one is given by this one and this is also as I told that we can find out this and then theta 1 f 2 pi by z 1 as I told and psi 1 is pi by 2 z 1 that is the half tooth angle. Then from the geometry what we find R p 1 is equal to R p 1 cos alpha. Now here I would like to say that if we have considered this R p 1 because R p 1 is something fictitious if you ask if you given one gear if you ask measure its pitch circle radius can you measure that you cannot measure you do not know what is pitch circle. Pitch circle is the circle when two gears are missing and if you divide the centre distance by the gear ratio then only you will find the pitch point and then only you will find the R p 1 ok. So, if we derived in that way R p 1 then we have to consider the working pressure angle if we consider this as a standard then we should consider the standard pressure angle. Anyway this expression is that R p 1 is equal to say alpha with that R p 2 is given by this one and the addendum circle radius of each gear is followed by the American Gear Manufacturing Association standard that is Agma standard in which according to their recommendations for the gear pump it is taken as the R a 1 is equal to Z 1 plus 2 divided by Z 1 in R p 1 which means the addendum factor is 2 by 2 is 1 normally in standard gears we follow that even for the gear pump the same standard is followed. Now, in design at first the number of teeth of gears are selected that means in non-dimensional analysis also we will be first tempted to take Z 1 is equal to Z 2 and we can start with say teeth number is for 20 degree we select the 20 degree pressure angle in that case we will probably we will take this Z 1 Z 2 very close to 17 which is the minimum teeth number for 20 degree pressure angle and probably we will compromise from starting from 20 to this side may be 16 not less than that. 16 teeth without gear correction is possible if we use the pinion cutter suitable pinion cutter, so in that case we may consider from 16 to 20 like that. Let us consider we have considered say 16 so 16 for Z 1 and Z 2 is also 16. Now, the average flow rate of pump in this case in this calculation we are going to show some results Q D average is very close to 0.3. So, it is taken 0.297 this is an arbitrary value one can one can take 0.1 also, but we have to be careful that from some absurd value all the data will be absurd. So, now we consider again this equations and M is expressed like this and in that way typical now we get the some result which is shown in the next slide in and 12. Now, there may be a questions for 12 number of teeth do we need a correction in general we need correction, but in case of gear pump the tooth load is not that high for power transmission gear for reduction gear box usually tooth loads are high if we use the steel and then for 12 teeth without any correction the root is weak, but in this case root is not that weak only problem is that we have to analyze the contact. So, that if the contact try to approach beyond the involute then there will be some problem again if a cutter is designed properly that is the pinion cutter we are considering the state tooth or in mass production definitely of cutter then it is also possible that with 12 teeth uncorrected the root fillet is not severely undercut. So, therefore, in this case because this is dimension analysis what we can consider simply we can say that this is the module used for the flow we will not consider the correction of gear teeth because with the correction of gear teeth then definitely this volume we have to while we analyze this contact point that will vary we must introduce that correction part in that analysis, but here in this case we shall not consider or this calculation in made without considering that these are corrected gear this is uncorrected gear. So, 13 and 12 then in that series that Z 1 we have kept 13 up to this point and it is varied from 12 to 16 then gradually we have increased the teeth number and we have that increase that driving teeth number up to 16 whereas driven from 12 to 16 that means in this case only say this is one case where both the teeth are equal similarly there is another case where both the teeth are equal and in case of this also 16 teeth there are 16 16 teeth. So, 13 13 then 14 14 then 15 15 and then 16 16 these two are of equal teeth if we only consider say these two as we find that definitely center distance factor is changing. However, if we consider the what are the flow ripples there we will I will show the graph, but before that I would like to take I have expressed that R p 1 and R p 2 may not be the standard one just mentioning the center distance we have to consider that R p 1 and R p 2 may not be the standard one just mentioning the center distance we can dimensional and say center distance we can mention what might be the volume because that will directly give us the non-dimensional flow rate we can compare with this non-dimensional flow rate with the center distance. Now say this is the center distance and this center distance non-dimensional center distance we have varied from approximately from 1.5 to 2.6 and then what we find with different combination of teeth say if we consider the blue line then that is with 13 teeth in the Z 1 is the 13 and Z 2 is varying from 8 to 20 we have calculated from 8 to 20 we have extended this graph, but in this chart was 13 something 13 was their minimum teeth number, but what we find that this is with the driving gear when it is 13 and this curve when driving gear is 14 and this is with 15 and this is 16. So, from this chart we can have a conclusion that the center distance increases strongly as the number of teeth on the driven gear increases and decreases weakly as the number of teeth on the driving gear increases. This means that you can judge this from this graph what we find that if we increase the number of teeth of the driven gear then this is this increases rapidly, but on the other hand if we when we increasing 13 to 16 then for a given number of driven gear this variation is not much whereas the if we change the driving gear one then there will be lot of change. So, from there we can have a some assessment what pair we should select for the pump, but again I would say that this normal practice is still equal Z 1 is equal to Z 2 and there is really not much reason that this number to be varied if there is reduction of noise flow ripple etcetera that is nominal not much. This results say that physically smaller pump of the same displacement per revolution may be designed if the number of teeth on the driven gear is decreased while the number of teeth on the driving gear is in increased. So, if we make the driven gear this is small and this is big the size of the gear pump will be smaller, but I would say this is not much still for the sake of optimization the size will be small. However, we are not considering what really will be to the noise and dynamics. The instantaneous flow ripple of the pump is given by the solution of equation 7 that is this is this equations and then we find that this is the flow ripple for different combination of teeth and this angle you can directly you can calculate by 2 pi divided by the number of teeth of the drive gear say Z 1. So, for example, if we divide 2 pi divided by no this is for half of the angle. So, pi by 13 how much it will be 3 divided by 13 3 divided by 3.14 divided by 13 will be approximately 0.25 or so no. So, this is 2 pi by 13 1 full cycle yes 2 pi by 13 and then 2 pi by 14 like this. So, I think this one for 16 teeth 16 teeth is 0.4 whereas, for the 13 teeth it is around 0.5. Anyway, this calculation is not that difficult, but you can see this ripple the ripple is increasing with definitely if the teeth number driving gear teeth number is small. Now, we should also consider the flow pulse amplitude which is expressed by this equation and then this we can if we plot this value with the driving increase in the number of teeth here and in this axis this amplitude then we find for different teeth Z 1 is 16 here and Z 1 is 13 and definitely amplitude will be higher for in case of small number of teeth and what the observation that strong dependence on the number of teeth on the driving gear. Otherwise, this flat is not this this curve is almost say flat you can say with the increasing number of teeth of the driven gear. So, we end here.


Hello everybody, Aaron Walker-Loud here. I'm the director and founder of Big World Breaks, and I'm brought here to you today by the creative advantage. We're going to be studying rhythm, percussion, technique, cultural innovation, and improvisation. You may have seen one of the other videos we've done, you may not have, but this one is Level 3 Challenge. So we look forward to pushing ourselves, myself included, because I always love a good challenge. I also want you to remember that no matter what equipment you do or don't have at home, it's totally fine to use whatever's available. Whatever the adults in your family feel is okay for you to use as a striking object. I'm using a table because this was my first instrument I ever used, a lunch table, and you may have pots and pans and wooden spoons. Use what works for you and make sure to get permission from the family. You may have a snare drum or a hand drum. Whatever is going to work for you, make it happen, and we're going to have some fun today. So as a teaching artist, I get the opportunity to study with other educators, work with students, work in the studio, work on stage as a performer and a producer, collaboratively writing curriculum with other educators. So I'm all over the map, stage, studio, and classroom. And I love the balance and working with students helps me become a better artist and working in the arts allows me to have more information and more inspiration to bring back to my students. So I'm very thankful to live this life that I do. And we've talked about rudiments in the past. We're going to do a quick review of some of the rudiments we've done before just to get our hands warmed up and to connect our brain to our hands. So we're going to combine all at once singles, doubles, triplets, and paradiddles, and we're going to do it at single time and then double time in sequence. So follow me, we're going to do it together. One, two, one, two, ready, and doubles, triplets, paradiddles. Okay, nice. Now let's try that two times in a row and see if we can keep up the momentum. If you prefer using the lowest pitch on the table, the fist, or knock, the highest pitch is fine. I'm using my open hands, the middle pitch. Here we go. One more time, twice in a row. One, two, one, two, ready, and it's okay. Now, now that we've done that, we're going to move over to the snare drum and start doing a little bit more advanced work with some rudiment technique that I've learned. Now, the five-stroke roll we haven't talked about yet, essentially like it sounds, there's five notes. So right, right, left, left, right, or left, left, right, right, left. Let's try that together. One, two, one, two, ready, and let's increase the tempo, the speed. One, two, one, two, with me. Okay, now we're getting a little more comfortable. What we're going to do is do three layers of single time and double time, and then we're going to eliminate the rest in the middle. I'll do it a couple times, then I'll pause just so we can clarify, and then I'll do it one more time. Here we go. I made a mistake, and that's okay. We're going to keep rolling with it. I'm human too. Here we go. One, two, one, two, ready, and okay. Now, that's a little bit better. Here we go. Let's try it again. One, two, one, two, ready, and all right. Now, I encourage you to find more rudiments. There's so many. We've dealt with singles, doubles, triplets, paradiddles. That was a five stroke roll. Let's revisit the paradiddles before we move on to something else though. The thing about my learning is that I've been blessed with a lot of teachers in my path, and when I got to community college, I met Mr. Brian Kirk, and he gave me so much knowledge, but specifically one of my favorite things is he showed me how to change the accents on a paradiddle so it makes it more challenging to where we can have accents and ghost notes almost like what we discussed in video number one. So doing paradiddles where we make the accent on every downbeat, and then we move the accent forward one note at a time every four repetitions. I'm going to do it once, and then I'll start speeding it up to make it more challenging. Here we go. One, paradiddles with rotating accents. One, two, ready, and so we got that. We know what we're doing. So now we're going to play most of them quiet and one really loud. Here we go. One, two, ready, and okay. Now the accents keep moving though. Instead of hitting the downbeat on the second time we hit on the third iteration, we hit the third note with the accent and the fourth iteration, same thing, the fourth note. Okay. Now I'm going to attempt to do that in sequence. Try that with me. Here we go. One, two, one, two, ready, and all right. So try that in different tempos and feels. It's really going to help your control with picking where you can hit accents on the downbeat and the up beats. Now what we're going to do is we're going to move back to the table to talk about a concept called 3 over 2 feel, and then we're going to apply it with some music on the jambé a little bit after that. So when someone says 3 over 2 feel, they're not talking about time signature 3 over 2. They're talking about a feel that's implied in music, right? And usually that's implied by the drums, percussion, or the rhythm section. Now if we were to take our lead low, whether it's your left or your right hitting the lowest pitch on the fist, that's going to be where we hit our downbeats on one and two. Then I'm going to show you how we apply 3 against that with our alternate hand using slap. Here we go. One, two, with me play along. One, two, then with our other hand. One, two, three, one, two, three, one, two, three, one, two, three, nice. Now let's switch hands to challenge ourselves but also to realize the closer we get to being ambidextrous, the stronger we're going to be overall as percussionists. Leading with the left hand now on the fist. One, two, one, two, adding three. One, two, three, one, two, three, one, two, three. Now another level of challenge we can do is rotate. You've seen I like playing with single time and double time. Let's try it with the three over two concept. Follow me. Here we go. Double time. Now for those of you who might be like, what just happened there? Let me just show you with one hand at a time. One, two, one, two, one, two, one, two, one, two, three, one, two, three, one, two, three, one, two, three, one, two, three, one, two, three, just so you can see but the trick is combining them. Let's try this one more time. Here we go. One, two, with me and double time. And last time double time. Not bad. Not bad.  All right. We don't want to beat up our hands too bad, but stretching and hydration will always help. Now that we've reviewed some of the three over two feel, we're going to move over to the jambé and try some of it live with some accompaniment as also using some improvisation as well. So there's some music that I put together with my team that I think would be a fun accompaniment for that. Follow me over here. So there's a lot of influences that came together for inspiring us to put this one together. Artists like Celia Cruz, Hector LeVoe, the Fania All-Stars, Yerba Buena, there's more than that, but that's a good starting point for you to check out some of their work. So we're thinking about the three over two feel against this. Let's start with tone, the middle pitch. Whichever hand you want to use, let's switch it where we have one of them playing on the two and the other three. One, two, ready, and okay. So once again, bass, middle, tone, slap on the edge. All right. So the idea is we're going to do single time and double time right now. So what we just did, and then switching it to double time, we're going to go back and forth. Follow me, play along. Whether you have a table, a drum, a snare, anything you got, it's totally fine. Here we go. One, two, ready, and double time. Let's try that again. Ready again. Free ourselves up. Let's do some improvisation. So rather than copying me, just do whatever comes naturally with your hands, with your sticks, whatever you got. I'm going to play a rhythm first, and then you fill up the rest. I'll show you where to go. Here we go. One, two, one, two, after me, freestyle. Two, two, three, back to me, and two, three, and let's do a couple more. All right. Nice. Back to me. All right. One more after this. All right. Okay. Nice. Cool. Now, as this music fades out, I'm going to return back over to the snare, and we're going to start looking at some more complex rudiments, subdivisions. When we're looking at subdivision at a greater level, the rudiment of doubles, which we've heard some of, start to get a lot more rapid to create what we call the roll. Have you ever heard of drum roll? When someone says drum roll, please. Okay. So there's different types of rolls, but essentially the fundamental DNA of a roll is two quick bounces at a time, back and forth. So instead of we increase our speed and our ability to bounce the stick using the force of gravity. So an easy way to start developing that for yourself is increase your tempo like a train, right? We end up, you know, getting a day at a time, you know, a little bit better, a little bit better. You got to be patient with yourself. So keeping in mind, we've done some of the other subdivisions and rudiments. Now we're going to get a little more complex. We're going to look at eighth note triplets, sixteenth note triplets, thirty second notes, thirty second note triplets and sixty fourth notes. Okay. So follow along with me. If you feel a little overwhelmed or whatever, just laugh at the mistakes and have a sense of humor and keep pushing yourself. All right. Here we go. Follow me as best as you can. One, two, one, two, ready. Okay. I've given you some clues about diving deeper into the challenges of subdivisions and rudiments, but you could have nine lifetimes and not learn at all. All right. So keep pushing yourself every day. We're going to be moving forward now, looking at a different concept, playing three against four, not three for time signature, but three against four feel. So we're going to move back over to the gym bay and we're going to pull up another one of the productions from Big World Breaks to help as an accompaniment for that. Follow me over here, please. So the song here that we put together has a lot of influences. I'm blessed to have been listening to so many types of music, had great mentors and family that was open-minded to what I was listening to. So all in a nutshell, I hear elements of Kendrick Lamar in this. Jimmy Hendricks, who was from my neighborhood, the Central District in Seattle. Buddy Guy, another great blues artist. Dungeon Family, OutKash, Goodie Mob, Janelle Monay, Buti Collins, Parliament Funkadelic, you name it. It's a big potluck of all kinds of sounds, right? And what I love about working with something like this is hearing the subdivisions and possibilities. We're going to focus on three over four first. So if I'm looking at 16th notes, counting it at this tempo would be one E and a two E and a three E and a four E. And if I take every third note, it would sound like how it doesn't carry over to the one every time, because it's odd going against even. Now what if I hit another sound in between that accents here, every third note, and then ghost notes in between, like this. Now that we've done that together, let's try and do it single time, then to double time. You know how I roll. We're always trying to figure out how to challenge it and switch it up. One, two, one, two, ready. Now there's a lot of variety. I would just use, but imagine, in your right and the different pitches here on a gym bay or a table or snare, there's a lot of options, all right? Now that we've gotten through all of this technical stuff and discussing, I'd like us to just get completely free. And now what you're going to do is you're going to battle me. There's no cash prize, there's no trophy. It's just about pushing each other to get better. So we're going to go back to the table, then come back here and go to the snare to finish, all right? So follow me over here to the table and we're going to do a little table battle. We're going to trade two bars at a time, just so you know what's going on. I want you to know the parameters before we battle, all right? So we'll be one, switch. All right, you guys ready? I know I'm ready. You ready? Here we go. Repeat after me anything you want. Be free. Ready? Then we've done a little bit with the table. Let's switch back to the gym bay and we'll start using some of our three against four concepts where you're three over two field. Do what you want. We'll keep freestyling. Here we go. Follow me back to the gym bay. I'll count us in. Battle round two. Ready? Here we go. After me. One, two, one, two. Let's get back to the snare. No matter what you got at home, it's all good, but let's get it. Follow me to the snare. Here we go. Time to shine. Here we go. Definitely burn some calories. This song fades out. I'm just going to help us review back over here at the table of some of the essentials we've talked about today. So it's been quite a journey. I'm really excited about everything that we've gone over. So once again, we've talked about some extra subdivision today, looking at quarter note triplets, eighth note triplets, sixteenth note triplets, 32nd notes, 32nd note triplets, 64th notes. We talked about some alternating ways of looking at rudiments with doing five stroke rolls at different tempos and eliminating the rest between the five stroke rolls. We looked at how to take a paradiddle and flip it inside out and add accents that move around. And you saw it was challenging me, so it's always good to review things, especially when they challenge us, right? We also talked about playing two different ways of three over two feel, looking at where your tempo is at, and then trying double time to see how your hands can keep up, alternating left and right leads, and looking at playing three against four, finding different ways to push odds against evens to develop tension and suspense while you're leading through improvising or creating your rhythms. And ultimately, as Mr. Nat, my original music mentor always told me, is that there's no shortcut in music. It's really important to be patient with yourself to remember that you're human and you can get better a minute at a time, but you can't get better just because you want. You have to decide what you love and put your time into it, and just be patient with yourself. And if you feel like you're not growing quick enough, find a way to put more time into it, all right? And I'm really excited to see what comes of all this work we have together and hopefully we get a chance to work together in person in a classroom on a stage sometime. Once again, my name is Aaron Walker Loud, director and founder of Big World Breaks, and this has been brought to you by The Creative Advantage. Thank you again.

Today on Six Sister Stuff, I'm sharing with you 10 three ingredient desserts.  So if times are tough or you just need a dessert really fast, these desserts are perfect for you. So if you guys are ready, let's get cooking. All right, so the first recipe I'm making is pumpkin cookies. Now I love that you only need three ingredients. So you need a spice, cake mix and go ahead and dump the whole thing in. Next you're going to take just a can of pumpkin, again, dump the whole thing in. Then just go ahead and mix it all together. Now it might take a minute or two for it to combine but keep at it, it will mix. Then you're just going to add two cups of your favorite chocolate chips. I love milk chocolate chips but you can use dark chocolate chips too. Then just mix that until it is well combined. Now to make these cookies, I love using cookie scoops or even an ice cream scoop. It makes it so much easier and they all are the same size. Now here's my secret. I usually put aside a few chocolate chips so I can put them on top so you can get the perfect cookie every time. All right, you're going to bake them at 350 degrees for about 10, 8 to 10 minutes whenever they are cooked on the bottom and yeah, they're still a little soft. The next one is my skinny banana cookies. I love making these if I'm looking for a little bit healthier of a treat. So I have two bananas here that I'm just smashing with a fork. You can use a blender or a beater's to whatever makes it easiest for you. Now once it is nice and soft, you're going to add one cup of old-fashioned oats into the mixture. Then you're going to add about a fourth cup of semi-sweet chocolate chips or milk chocolate chips, whatever one you choose. Then you're going to mix it well. It's going to take a minute to get everything wet but just give it some time. Again, I'm using my cookie scoop because I love using it. They're all uniform and they all cook the same. So that's why I love using a cookie scoop. Now you're going to cook this at 350 degrees for about 12 to 15 minutes until they harden up and they are cute little banana cookies. The next one is rollo pretzel turtle bites. Now I would suggest getting smaller pretzels than I have here because the rollo did not want to stay in the middle. So smaller pretzels is a must but they still worked out. So you're going to put a rollo on each pretzel. Then you're going to cook it in the oven at 350 degrees for about three minutes. The rollo's are going to be melty and all you have to do is put a pecan on top and you are done. Next up is three ingredient Reese's fudge. Now it really is three ingredients and you guys, it is one of my favorites. So you're going to take a nine by nine square pan, line it with foil and then spray it with non-cook cooking spray. Then you're going to take your Reese's. I had a very good helper helping me today. We're going to do 16 on the bottom of the pan. Next you're going to take three cups of chocolate chips and then just dump them into a microwave safe bowl. Now you could do this on the stove top also but I love using the microwave. Then you're going to take one can of sweetened condensed milk and just pour it in over your chocolate chips. Then I like to microwave in 30 second increments and then stir in between each 30 seconds. Then stick it right back in the microwave. Now once everything is melted it's starting to get a little bit thick. This is how we like it. So now it's time to put it onto your Reese's. We're making the rest of the fudge. Go ahead and pour it on very gently. The Reese's might come up a little bit as you're spreading so just try and hold them down as you spread. Now it's time for the topping and of course it needs to be Reese's. So I started out with 22 Reese's. I put 16 on the bottom and the rest I am just crumbling up and I'm pressing down into the fudge. So when it cools and hardens the Reese's will be stuck in there. Now I let this sit in the fridge for about an hour and a half and it is hardened and ready to go. So I'm carefully pull away my foil and then you can cut right into it. Now I love this fudge because you don't need a candy thermometer and it actually keeps its shape pretty well. I also love that you can see the Reese's on the bottom and on the top. Now whenever I make this fudge it is gone instantly. Next up is my luscious lemon cake. Now I love this because you only need two ingredients. So we have lemon cream pie filling and then one box of angel food cake. That simple. So you're going to dump the whole bag of your angel food cake into a bowl and then you're going to just add in your lemon filling. Now I would suggest mixing very carefully at first because that cake mix will get all over. Once it's combined a little bit then start using a whisk and it will make the job a little easier for you. Now I sprayed a 9 by 13 pan with nonstick cooking spray and then you're just going to dump in the batter. Spread it around as evenly as you can but don't worry it will cook and it will even out pretty well. Now once it is pretty even you're ready to bake it. You're going to bake it at 350 degrees for 20 minutes and it really turns out perfect. This is angel food cake with a lemon into it. Oh it's so good. I like to add a little bit of whipped cream and then some strawberries on top all together. This thing tastes amazing. Next up is cookies and cream pretzels. Now you can use any pretzels for this. I found some cute little round ones so I thought I would give those a try.  You can use white chocolate chips. You can use whatever you want but I just did a little bit because I don't need a ton. This is a perfect after school snack for my kids so you're going to go ahead and dip your pretzels and then put them on a lay out some foil. Put them on the foil so they can dry. Then you're just going to add a little bit of crunched Oreos. It just gives it the perfect amount of flavor with the chocolate and the pretzels all together. It's so good. Next up is M&M fudge. This is so simple because again only three ingredients. Now you're going to be on low medium heat. We're going to add two cups of semi-sweet chocolate chips and then just one 14 ounce can of sweetened condensed milk right on top. Now as this starts to melt you want to make sure that you keep stirring it because you don't want anything to burn onto the bottom of the stovetop. Now once it's all melted you're going to go ahead and add three fourths cup of those little mini baking M&Ms and just mix them just until it's combined. No more than that. Then you're going to take a nine by nine pan. Make sure it's covered with foil. Spray some non-stick cooking spray on it. Then go ahead and spread your fudge all along the bottom of the pan. Then you're going to take the rest of your M&Ms and gently put them on top. Then you're going to press down so as the fudge hardens the M&Ms will stay in the fudge. Now I like to keep it in the fridge for about an hour or two. Let it stiffen up and then go ahead and remove the foil. Gently cut into it and then you're going to have perfect fudge pieces. I like these because they stay in their shape. They're not really gooey. They are perfect every time. You don't have to use a candy thermometer. It really is the easiest fudge recipe. The next recipe is banana bread or kind of like banana cake. So you're going to start with two bananas. Overwrite, go ahead and smash them up till it's nice and smooth. Then on top of that you're going to add half of a package of a cake mix. Now you can double this recipe and use the whole cake mix and add more bananas but I didn't want a ton of banana bread so I'm just halving the recipe today. So I used half the package. Then you're just going to add one egg and then mix it all together. Those are your three ingredients. Now once it's all mixed together and pretty smooth I mean you will have a little bit of banana chunks in there which is I think delicious. You're going to go ahead and spray two small pans. Then go ahead and try to even out your banana cake batter. There we go. So each pan is about filled the same. Next you're going to preheat your oven to 350 degrees and you're going to cook these for about 30 minutes. Now if they need to cook a little more go ahead and do that but I like them a little bit golden brown and they are super soft in the middle. Up next is my two ingredients strawberry fudge. Now this is super simple because you just need two ingredients. You need strawberry frosting and you need white chocolate about 12 ounces of white chocolate. So you're going to go ahead and dump your frosting into a bowl and then you're going to add your hardened white chocolate into it also. Now you want to make sure your bowl is microwavable. Then you're going to microwave it in 30 second increments just until everything is melted together. Now go ahead and set your frosting mixture to the side. You're going to get a nine by nine square pan. I lined mine with foil sprayed a little bit of cooking spray and then you can dump your strawberry fudge right into it. Now it went pretty flat on its own. Now I'm going to add just a little bit of sprinkles because you know I have lots of little girls and they love the sprinkles. So we're going to add a little bit of red sprinkles on top just to give it a little extra. Now I stuck mine in the fridge for about an hour until it was nice and hardened. Then you can pull it out pull off the foil and it's time to cut. Now I know what you're thinking it's a little odd that it's just two ingredients but I'm telling you it is my kids favorite kind of fudge. Now of course I need an instant pot recipe in here so I'm going to make dulce de leche or homemade caramel. So we're going to start out with a 14 ounce can of sweetened condensed milk. Now I'm actually going to cook it inside of this can so we have to take the wrapper off. Now once the wrapper is off this is the most important part.  You will have an explosion or something horrible so make sure the lid is off. Now to make it a little bit easier you want to put something down below. So whether it's foil or a trivet something so it's just not right sitting on the bottom. Then you're going to cover your can with aluminum foil. Now make sure it is sealed tight as tight as you can get it. Then you're going to put your can just right on top of your trivet. Next you're going to fill up your pot until the water is about halfway up the can. Now although it's hard to tell here the water is filling up and when I'm done filling it up it's halfway up the can. So now you're going to put the lid on make sure it's really tight and sealed correctly and you're going to turn the knob to ceiling. Now depending on which kind of instant pot you have this instant pot has a pressure cook button or if you have a different one it could have a manual button but we're going high pressure all the way up to 40 minutes. When the 40 minutes is up go ahead and turn the knob for a quick release and then take the lid off when all the pressure has released. Now you're going to want some sort of oven mitt to pull out your can. You can use your trivet but for me it was easier just to use my oven mitt and pull it right out. Now for my favorite part it's time to take the foil off of the can. Now if I would have known that it was this easy to make I would have made it many many years ago. Now the caramel or caramel is a little thick right now. The goal is to get it nice and smooth so I like to dump mine into a bowl and put about a half a teaspoon of vanilla on top and just start mixing. Now keep mixing because it will get smooth and it will start to set up. As soon as it sets up you can serve it with apples. I like to serve it with a little bit of sea salt on top. Now I just had a recipe a few weeks ago where I made some caramel poke cake. That would be delicious on this poke cake. Now if you love these desserts you're going to love our three ingredient dinners you can find that right up there and I will see you guys next time. See ya!
