Good morning everyone. It is currently at 7 30. I am back in LA now. I got back last night I am just finishing up some upload stuff and then I'm gonna head off to orange theory I have a class at 8 30. I haven't done orange theory. This is the longest I've gone without going since I Started so I'm probably gonna die this morning So that'll be super fun But today I'm just going to be getting back into my routine reorganizing cleaning everything. It's basically like a post Travel day like what I do to get back in my routine and then tonight Maddie you guys have seen her definitely on YouTube I feel off with her. I'm obsessed with her. She's in town. So we're getting dinner, which would be really fun But today is just gonna be like a really getting your life together day and I'm excited about it Oh my gosh guys is kind of sprinkling and so gloomy. I am so happy if you guys know me You know that I love this weather I'm so happy that it is like this. Okay, so I have my swell bottle Trying to show you guys what I take to orange theory. I take in my purse But I just I don't use it. I don't know why I take it in and then Guys, I swear. Where's my heart monitor? This isn't funny my heart monitor If you guys watch my vlogs, you know that that goes missing all the time I just like need to know where it goes like it's just bizarre and then I take in my heart monitor But it's not here like it's always in my car. I leave it in my car because not because You know what? It's probably my gym bag. Okay guys. I found it. Thank God So basically these are my must-haves for orange theory my purse my swa water bottle whatever water bottle I'm bringing for the day. Sometimes they're my hydro flask. It just depends and then my hurry monitor I'm dead. I got my pink flamingo smoothie I get this with peanut butter and I get the 24 ounces of the best breakfast honestly That might be too much for me today. Just finished orange theory. I died I like actually died like I'm so dead, but I'm about to do a little bit of shopping for my house I'm gonna put AirPods in and listen to a podcast because they really don't want anyone talking to me like at all Can't do it right now So I'm just gonna shop a little bit and see this camera is still dying. I will talk to you guys later All right guys, so I'm sorry that I didn't vlog much while I was out running errands. I ran errands for like three hours I did a lot of shopping. I have possibly the biggest unboxing slash haul to show you guys I'm gonna go shower and then I will do that But like seriously and let me show my groceries So I think I'm gonna do my groceries shower and then show you guys like I'll give you a little sneak peek Well one thing you guys can't see today, but I very exciting thing. I finally replaced these chairs. They're on their way They're gonna come tomorrow this green Rug that's gonna be awesome. So basically picture this green rug here and then green velvet chairs And it's all just so much better. I just did so much shopping. I got some silver Ross Look at how cute this thing is you guys will see but I'm like absolutely obsessed with it and Then I got a bunch of candles at Target because they're having a sale Which is only 15% off which is literally a dollar off the candles So I was basically scammed and then I have all of these boxes I don't want to get too close because I don't know if my address is blocked, but I have let's count Yeah, so there's a and then I have this huge box from battle proteins that I'm really excited about because I recently am like I'm not a collagen kick. So it's good. All right guys So I am going to do a little grocery haul. Oh my gosh. This is so much darker. No Okay, I'm wanting my DSLR because I left my G7 X charger in Texas, which I have done this so many times guys. I probably spent $600 at least on G7 X chargers because I always forget them when I travel it's so annoying But I'm gonna do a little grocery haul for you guys and show you guys what I got All right I was actually already recording this and then my camera messed up so I have to re-record it Okay, almond milk brown rice definitely want to get couscous chicken dates Strawberries for salads Brussels sprouts. I'm actually gonna make this really cool Brussels sprout like Bacon maple syrup dish that I will show you guys very exciting Um, I almost said almond milk. These are definitely avocados. No, no, no These are just grilled strips for like grilled chicken strips that I'm just gonna throw in salads Here's the bacon. I don't know who this is or still my counter blueberries maple syrup goat cheese so guys I really like goat cheese on my salads, but Trader Joe's has like no selection I don't think that's even gonna work for salad. So I guess we'll see eggs balsamic vinegar Walnut halves for my salad that is not mine Kale and then some more lettuce. So this is what I got from Trader Joe's It is a very very exciting little overview So the really exciting thing today is that I ordered a lot of kitchen stuff and kitchen replacement So I'm gonna be like reorganizing. I base. I'm literally doing so much. We are unpacking reorganizing Unboxing all that stuff throwing away all that trash. I'm just gonna take a second I got some new house stuff that we're gonna be setting up. It's very exciting. I'm very pumped for today So I'm gonna put this away and then I'll talk to you guys once I shower. All right All right, so I just got ready really really quickly like a no makeup look. I put a little bit of mascara on I'll show you guys the products that I used. Okay, so the first thing I use is this tiger grass cream I mentioned in a past vlog look at also these these Sweats guys what a major throwback if you know, you know comment down below if you know Anyways, this tiger grass cream. I don't feel like it cancels out my redness as great It just doesn't really at all. I just like it as an actual moisturizer But the doctor jar tiger grass cream in the jar Completely cancels your redness out. So if you guys are looking for that get the jar I wish that I would have gotten the jar but I got this and I like it as a moisturizer It makes my skin like still feel really good and very moisturized So that is I don't know then this Laneige lip mask. I got because Maggie McDonald always talks about it It's amazing. I absolutely love this. I love lip products and this is like one of my favorite I've ever used so I'm really excited about that and then I just brushed up my brows and put a little bit of mascara on and That is my look for today So I need to unpack this pretty bad, but I'm gonna do that later I'm gonna completely clean my room and do all of that in the meantime. I have this laundry I need to do first so great. Okay, I am going I don't even know where to start I have so many things to unbox. This is the unbox haul part So we'll start with Ross the closest one to me.  Okay, I Got this little kitchen aid whisk because it was four dollars.  I can't even focus, but I just don't have You know when you go grocery shopping, you get all this stuff to meal prep like I'm planning on meal prepping today But I'm not gonna eat something like that. I'm making right this second. So I ordered food Um, I ordered to Kaia and it's on to a to Kaia is like actually the best cute kitchen aid whisk with a little It's just cute, you know Then I got these little Coasters to put on the kitchen table since I'm Fixing this area. This is probably my favorite thing I got. Look at how cute it is I'm just really excited for this a nice cute pink pot Love it. I honestly want like an entire kitchen set in this color because it's so cute But I'm very excited about that. I have this really really really big bag from Ross I got two pillows two of these for the couch And then I got this little rug that I'm just gonna put in the entryway because it was so cheap I got this really big. Oh Joe's coming in got this really big green large rug It's amazing. Okay really quickly. I'm gonna go through the Candles that I got a target. Okay. I don't like the tacky looking candles You're really gonna like bath and body works are like ugly. We have to get on this, you know I like all the anthropology candles. Those are my favorite. It's really expensive But I got these from Target very cute Got another one of these smells actually amazing. I'm gonna put them out here, and then I got a candle That's like a eucalyptus scent that sounds really good That I'll put in my bathroom because I have a lot of like eucalyptus stuff in my bathroom It's very relaxing. I got this little as I said a fuser I've never had one of these But I also like the look of this for out here on this table this little corner area that I'm fixing And then I also got a frame because literally all the frame says is the reason that my office is taking so long for the Frames is because none of them are normal frame sizes that I think society six says I'm on purpose So you have to buy their frames, and I wish I would just bought the frames to begin with But I got that one to see if one of them fit works with it, so I guess we'll see but it's just so frustrating On to the billion Amazon packages and orders that I made over the past week when I go home I just think of all the things that I want and need to buy and then I just get it all the time This is very exciting. Okay So I got the voting game so I got the an expansion pack and in here somewhere I got the normal voting game. So basically I host family game night slash dinner family dinners weekly It's a very big thing. It's a very I'm very excited about it. You know Monday. We're doing John and Finney's pasta very pumped I'm gonna do a whole vlog to unlike how I prepare for that and like how I host it basically very exciting We play the voting game. This is my favorite game. I will have a link down below I hate games and I love that one so it's good. Okay, so this is a PR package, but this is from pharmacy I didn't realize how expensive pharmacy wasn't taught in the Sephora recently But unless I'm thinking of a different one. This is their honey grail line So ultra hydrating facial oil very sad for that. I don't know if you can even I'll test it out and then Our hundred percent raw all natural buckwheat honey from California. Oh, that's so cute. They even honey So thank you so much one of my four large Amazon Packages. Oh my gosh, okay I got more meal prep containers and then I got a 15 pack of mason jars But I feel like these are a little bit smaller and I wanted these for overnight oaths That was my vision behind it didn't realize there was 15. So I don't know what I'm gonna do with all of it Okay, the next one I got a knife set. I have never had like a big knife set Since moving out, it's I've almost been moved off like four years now Which is crazy to think about but like literally for four years and gone without like large knives Which is very difficult when you're a chef now, you know, so I had to get more I got new mixing bowls because minor trash and I really just needed new ones So and then I just got new cups instead of eight of them. Very good Oh, I got new bedding I'm gonna replace my bed too. So I just got I wanted to be very like hotel room vibe So it's all white. So that's really easy. I got these two little more bowl jars I can't say it. So I just got two of these. I'm gonna put cook and it's treats in them throughout the house. So I Can have them ready. Okay, I got two pillows That are packaged so tightly. This is just two new baking pans So I'll show you guys more of this in the kitchen But okay, so a vital proteins just sent me a package Which is convenient timing because I'm getting into college and now so very very very exciting But basically battle proteins pure collagen and nutrition. So they gave me collagen water Collagen peptides and then collagen shots. So this is the apple cider vinegar and raspberry and lemon This is the chamomile and lemon. There's so many shots. Thank you so much for the proteins. This makes me very excited But yeah, collagen shots cleanse. I'm very I'm like actually so pumped So this one is the cleanse and this one is the Zen which makes sense because it's chamomile lemon But I will keep you guys posted on how I like this stuff. I'm so excited Okay, so here are my new kitchen supplies. Here's my new knife set This was really cheap on Amazon. So I'm sure it's like not a great knife set But I just needed something like I literally have never had anything got new mixing bowls new cups new baking pans Okay, so I accidentally got 15 of these but these are like the perfect size for overnight oats The mason jars that I use are always like there's just too much food And then you don't finish it all and it's really annoying And so the cha cha matcha ones are probably like two-thirds the size of this But this is honestly like just I feel like the perfect size for overnight oats So I don't know what I'm gonna do with 15 of them But that's perfect and then I got more meal prep containers. I have meal prep containers, but mine have Like compartments in them and I wanted some that didn't have compartments in them and then my beautiful pop That's so cute like guys. Have you seen that? That's just so freaking cute Just threw away all those boxes took me 15 minutes. Okay. This doesn't look organized But it is so I'm gonna take all of these is your dirty clothes these are clothes that I don't want to wash the same way and I'm gonna take these to the washroom and Do some laundry? Okay, so I just ordered to kayak off caviar. I will have my Code down below if you guys live in LA Basically, you get free $20 credit if you use my code. This is not sponsored or anything I just love caviar and it like covers food. It's not just delivery services So this was like a $25 thing and I got it for eight Amazing. Okay. So the tachaya was incredible again guys caviar is also my favorite food delivery service It's better than postmates. They always have deals like I literally got a $25 meal and delivery thing for $8, so check them out I think they're only in LA. I'm so sorry. I don't know but I tried the vital proteins collagen water and it's really really good So I'm a fan of this. All right, so I just unpacked all that stuff and then I just Um like it got my comforter out my duvet cover my pillows set all of that up I'm gonna get a white bed and I'm gonna get rid of this. The only thing is that I'm just so intimidated I'm like getting rid of all this stuff to like take this apart I just I don't even know what to do like I had someone set it up actually no I had friends set it up into my movers rebuilt it So I just don't even know like I just went out of my house so bad So maybe I'll hire a handyman that's like from toss grab it or something, but it's gonna be so much better I really want my room. I feel like there's studies and stuff that say your room should be the most like Like bear place like even the clutter that I have right now is too much But I just want to be all white and like all very minimal and just very like mature So I have a few more things I need to order and then I think I'll be good Alright guys, this is like set up really weird, so I don't know what's gonna work it on So I'm currently on my way to Starbucks right now I really just wanted to try the nitro cold brew with coconut milk. I never thought about putting a milk in it I just wanted to try I always get a cold brew with coconut milk And I want to try the night for one anyways I have a lot of stuff that I need to get done So I thought that it'd be nice to get a little break because I've been cleaning and organizing and just running errands all day So since I've been doing that I really just need to see get out take Coco on a walk get a coffee Wait, I just want to get a coffee and take Coco on a walk and then go work in my office I need to add it a little bit and then I have some schoolwork So oh my gosh, this Starbucks line is actually really ridiculous right now. It's never this bad whoa Coconut on me I changed into this top that I got From loft they sent it to me and it is literally the softest thing I have ever worn like ever Anyway, so I've gotten pretty much everything organized thrown out. I took at least 10 trips in the trash can. It's so bad I got rid of a lot of stuff and then I also like obviously most of it was the packaging I just needed a midday break where I would get out and I really it just blew me out I love this weather really just wanted to take Coco on a walk with my coffee So getting my coffee and then we're gonna go to walk and then I'm gonna get some work done on my office You guys will see that so I'm very excited I will start with so I'm gonna get real. Hi. Can I just have a grande nitro cold brew with coconut milk, please? Thank you Okay, so I got a grande Nitro cold brew with coconut milk. I will taste test in a sec. Oh, I think I do like it better Then just the normal cold brew. This is the nitro one which I like it I had it without the coconut milk the other day and I didn't like it as much But like I don't really drink just cold brew black I drink every like my other coffees black, but normally with the cold brew from strawberries. I get like a milk in it, but I'm a fan Okay, so I'm in my office right now, which is very clean the carpets got clean last week and I haven't really been home So I have my cold brew. I've barely finished it You can't even get this drink in a bigger size than a grande because that's how much caffeine is in it Like they won't give it to you. So that's great I'm just editing a vlog that's gonna go up tomorrow and just planning out some stuff I'm gonna do a little bit of school work as well. I am in summer classes, which is just so fun I'm only in lemon two, but I'm only in one right now because there's like two sessions So I'll be in one each session. So I need to do that and get some work done I'm just gonna like crank out a bunch of stuff in the next few hours. I'm excited. Okay. It's currently seven I don't have my dinner reservation until now. I really don't need to leave until like 8 20 because I need to get gas So I have like an hour and 20 minutes I don't know why I'm trying to get ready right now because it takes me like literally no time to get ready I've been working slash. I was FaceTiming Molly for like two hours And we were working on dates for the Boston trip, which is very exciting. So I got a vlog uploaded for tomorrow I did some schoolwork Did some schoolwork and yeah, I put away some laundry I've just honestly done a lot of stuff.  I also need to get a rug guys. Okay. Here's the thing I'm just so over every like I want my house to be a little more mature Which like it's not gonna be more mature with like this, but I need a big rug right here I want like a very big one and then once I have the rug there. It's gonna be so much better I need to take this down. This is totally my bad part of me just thinks that we're gonna want it for something I don't know why I think that for like a backdrop or something I'm gonna keep it and then throw it away at this whatever, but this is like the studio set up I don't really know how to I got the white thing to be like way too wide So we can't put it this way So I don't really know how to make this look neat Because like it's just a bunch of equipment and we need this open space But once all of this is set up. I feel like it's just gonna look so much better I'm so excited like literally so excited and I want to replace this stuff right here because our Texas thing I was showing Molly this if this is from urban and we've had it for like a year now, but it's just like falling apart I don't know why like how that happened, but it's just falling apart. So that's not good not good at all So for tonight, I am oh, I don't know what jacket. I'm gonna wear I wish I had like a really big oversized bomber like a sports bomber or something dang it I'm just gonna wear this black turtleneck because I'm very pale right now And I just want to throw my hair up in a bun call today be done, you know Jeans these are a little bit big on me, but I really like garage jeans, but they're super small like I'm a size like 25 and I wear size seven in these jeans So like that's like I feel like that's really off and then I'm hopefully gonna wear these shoes from urban Then I got I still haven't worn them also Sav and I are going to Malibu tomorrow and we're gonna shoot so I'm just kind of getting some outfits together for that Just so I have options that we can bring and I'll just have them prepared for tomorrow I just want a bunch of like cute dresses. Oh my gosh. Why is it like this? Okay, so I went ahead and I packed my gym bag because I have an early class tomorrow morning at like 730 Just so I would be prepared and I also laid out all my outfits for tomorrow I will show you I have a big day. We're shooting and doing a bunch of stuff So just like I said earlier. They're right here. I love having this mirror here because now I can like Okay, my room looks so much better in real life and it doesn't person. It's very dark on here very annoying But for my outfit tonight, I'm just wearing a black turtleneck black again the Olivia J jacket Jeans these are like my favorite BDG jeans Guys, I just like don't have any jeans such pants I'm like I feel like are flattering that I like like I just don't like any of my pants I don't feel good at any of them So if you guys have pants that you feel like are very flattering Let me know in the comments down below the most flattering jeans not like fashion Nova jeans like I don't want like skinny jeans again I want like cool Pants I don't want like just like skinny jeans. You know what I'm saying that are like like that's not my vibe So yeah, and then I have these shoes from urban I changed the jeans. These are not the garage ones. These are the urban ones because the garage was just like I didn't look that good. I also actually did makeup tonight. So I'm wearing Eyeshadow, which is crazy Today I just want a really good day, but anyways, I have hoops on gonna put my earrings on or my rings on Just like my normal whatever nothing too crazy I need to get a different jacket because I wear this one all the time But it's because it looks good with everything like I need a jacket that like I just need more jackets Even though I have like 17,000 jackets. I'm aware. I need more So I'm gonna try to give you guys like a better Look Sorry, my neighbors definitely think I'm very weird So this is the outfit see I like having this So because it's very nice this lens you can see so much Okay, so I am going to obviously leave this camera here I'm not gonna carry this and bring this grassiest modray, but I'm going to grassiest modray with Maddie I'll have her channel link down below you guys definitely give you like my videos You will love her videos. She's just so cool. She's in LA for like two days I think so I was like here. We're definitely getting dinner So we're going to grassiest modray, which is one of my favorite restaurants in LA. I get the chimichanga It's the best thing ever.  I think then I'll see you guys when we get home It wasn't even recording. Okay, we're at grassiest modray with Maddie. We got chimichangas.  It was really fun I'm so full. I'm so tired and I have to wake up very early tomorrow So hope you guys enjoyed today's vlog It was a lot and like all over the place, but hope you guys enjoyed Let me know if you guys did really make comment down below this week I'm doing things like not every vlog is gonna be me from my house working and growing orange theory Like there's gonna be other things and I am gonna do different Venice classes. So don't worry I feel like things to get really repetitive, but it also is my life. So Yeah, let me know you guys want to see vlogs. Love you guys so much and I will see you soon. Bye


We'll do one of those as a warm-up and then we're going to look at another way to do some of the very same problems, then you can make your choice of which one you think is the yummiest. So imagine we've got running in a track of some kind, some little roller that happens to be attached to an arm that is at 45 degrees. Now remember, a lot of these problems, just to get through them, to be able to do some stuff with them, we have to say this type of thing where we say at this angle, find a velocity. At any other angle it's going to be a little bit different than these things tend to run through cycles of some kind possibly. So it's a little bit artificial. So if you go into this business you're going to need to know what these things are doing at all times, not just at one single little angle, but we're just getting started here. So this happens to be 45 degrees and this angle here is 60 at the moment shown. And a couple of the lengths, let's see, this is 125 millimeters, this is 300, and that arm happens to be turning at four radians per second. So we want to find the velocity of the roller in the slot, so maybe I'll call that D. You'll find out shortly why I've left C out of it, it's not that I'm prejudiced against the letter C. Gosh, that would throw out 126th of all the great Sesame Street episodes right there. I just can't have that. All right, so we want to find out the velocity of D. All right, what we'll work with on Friday if you remember was the relative velocity equation, the fact that the velocity of any one little piece of something is going to be related to two things, one, the velocity of any other piece of that, and remember this only holds for a rigid body, you can't do this from one body to an X. This is a rigid body equation and it's a vector equation, don't forget those two things. So the velocity of one end is related to the velocity of the other end, plus what the relative velocity is between the two, D relative to B. If you were sitting on NB looking down at D, what would it appear to be doing, remembering that it's, again, a little bit of an artificial construct here in that if you're sitting at B, you'd have to ignore the fact that they do yourself for moving. If you were moving at constant velocity, you would only have visual clues anyway that you were moving, as often happens in the car. You know, you're going down the highway, you don't know you're moving unless you're looking out the window, other than you bump on a little bit. So that is for a rigid body and is a full vector equation. So if we want to find out the velocity of D, then this is as good a place as any first to start. This is what we're working on Friday. The thing to do is start putting together what you know and what you don't know. For example, V, the velocity of D, well, due to the fact that it's in the slot and due to the fact that things are going this way at the time, we know the velocity of D must be down that slot and in that direction. It just can't do anything else. So we can use that. We can say, maybe we want to say V being in the I direction, maybe just keep until our normal orientation. We'll call that the minus I direction. It doesn't have to. It doesn't matter what we're looking for is the magnitude of it anyway, but you have to be consistent with anything else that goes into it. The velocity of B, well, that's the same thing in that B and A make up a rigid body as well. So those are also subject to this relative velocity equation for rigid bodies, except there's a little bit of difference. Point A is not moving now in this problem. So B is going to move relative to A. Well, we can envision just what that's going to be because this rigid body, the arm, link arm, A, B is pinned down at one end. B is only going to go in that direction. It just can't do anything else. Now, you can use the geometry of the problem to come up with just what that angle is, but you can also use the relative velocity equation that we are using on Friday that this velocity, this relative velocity can also be found from the cross product of the angular velocity with the position vector between the two. And if we could do that, that would be put in here for B, B. And we could do the same type of thing for the relative velocity in D to B. The angular velocity vector D, B crossed with the position, relative position vector. And that's the kind of thing we are working on Friday. All right. So if you need to see it visually too, though, this, all of these equations have three components to them such that if you look at that equation in graphical form, it must form a perfect closed triangle. And for some of you, maybe that's a better way to solve some of these problems. For example, we can look at it this way. We know that the velocity of point D relative to point B is always perpendicular to the line connecting the two. So that's got to be the velocity of D relative to B. Because if you were sitting at B, point D couldn't come any closer, couldn't go any farther away by our definition of a rigid body. That means it can only go to your left or your right as you sit at point B, looking down the arm at that. So we can draw that as a rigid or as a vector triangle and maybe for some of you that can help sometimes. So VB looks something like that. I'm not sure just how long it is, but I know it's going to be in about that direction, VB. Add to it VD, which has got to be something about like that, VB plus VDB, those have got to add together to give us the velocity of D, which we know is horizontal. So we know that these two, we know that those two, the original part of these two vectors must have equal and opposite J components for them to end up as a horizontal vector. So either way you can now solve this, maybe use in law of sines and cosines, or you can use it as the components or however you want to do it. Either one, they're fundamentally the same thing. It's just for some of them we need to do this at least to come up with a magnitude. So that's what we were working on Friday, a slightly different view to it. Actually another way you could look at it, just in case you're not confused enough, here's DV. We know that D has to go that way. We know that V has to go this way and we know that they can't get any closer together. That means they must both have the same velocity along its own length, along the arm's own length. I don't know what we call that. Velocity, I don't know, what? What do you want to call it? Quick, I don't know. Something. V, two. I don't know. V prime. We'll call it V prime. Two components must be the same. Otherwise point D and point B would be either getting closer to each other or farther apart from each other. All of these are the same thing, are perfectly equivalent to each other, and may help you see what's going on a little bit that a one may be more of your liking than the other. So if you like vectors and cross products, there you go. You're in hog heaven, right? Vector cross product heaven. This is it. You like the graphics and semi piece of each, there you go. So give it a try. Whatever you like, whatever works, see if you can come up with a velocity VD in the next couple minutes here, working together. What would Jay be talking to anybody? Not his name. Jay, we used to be so close. The order in which these are read, whether it's on R or B, and we're going to have acceleration on Friday, it's if you're at A, where is B? Or if you're at A, how is B moving? So it's always drawn, the vector itself is always drawn from the second letter to the first. So bats are D relative to B. And you do have to have that right if you're doing the cross product. Boy, you don't have to have it right if you're... Well, I guess you don't need it through the diagrams, particularly like doing cross products. But we have found on these 2D problems, they're fairly straightforward ones because the vector in which they result is only going to be in the Z direction. And there's really only one component to it. Can I find this? Not the whole component. Remember, there's two unknowns, because this is a vector equation, it's really two equations. So the two unknowns would be, well, VD, you're going to know from there, VD and omega DB. And you could solve the equation, I think, so that you can avoid even finding that. Do the right ones. Elimination first. These are full vector equations. So don't come to me looking for help if you don't have vector signs over them. Doesn't hurt necessarily to find omega DB, just to make sure the sign is right on it, because you know in what direction it should be rotating. You can comment this in your algebra. Yeah, you do. Because you need... Well, you don't have to if you can find DB some other way. But you need not just the magnitude of DB, you also need the direction that you can get that from this drawing for this one. So no, you do not need to do that if you can do it from the diagram itself. The, what, the 30 degree angle here. Half heads is of, half weights is a full width. Equations. So an i component here, an i component here, and they must be equal to j components, and they must be zero. D has no j component to it. Automatically, what's the vector DB? That was omega, omega DB you have there Bobby? Yeah, yeah, 6.79. Yeah, that's what I had too. So once you've got that, then the DB should be just the next part you pull out of it with the, must be a math error, because you've got the right angular velocity. You've got the right thing here. So as long as that's right, well, let's see, as it, as it moves, this is points going to get a little bit higher. So it's going to have to go something like that. It's going to turn in that way. So omega, omega DB should be positive. Do you think you've got a positive for omega DB? No, these are millimeters. Millimeters squeezed in there now. It's all in millimeters? Yeah. It's just a decimal place though. Sometimes you use them, sometimes you don't use them. Well, sometimes it is DB in the I direction. It's not minus this, it's minus this magnitude of the direction. And then, when you do this side of it, you should have a couple I components you can put together, and they must equal that. And you'll have a couple j components together, which will equal zero, because there is no j component here. And that's the same thing as you see here. When you put these two vectors together, you end up with no j component. Where to get the omega DB from? This is two equations, because it's a vector equation in I and j directions. Two unknowns. VD, the magnitude VD is unknown, and the magnitude omega DB is unknown. So you can solve those two equations for the two unknowns. You might be able to solve this without even bothering my bad unknowns, since it wasn't asked for it. But I don't remember how the algebra shakes out. Yeah, it looks like you're going to have to find omega DB in the j direction, and then use it in the I direction to finish the problem. Okay. So Bobby, did you find your mistake? Is it a little math error? Yeah, I think it is.  I don't think. All right. We're going to come back to that in a second as we look at another method. So we'll start with a clean drawing when we get there. We've seen from other things we've done that anytime we have a rigid body rotating about some particular point, in this case I'm going back to a quick discussion of pure rotational motion, no translation. Then we're going to use what we've got here to go to the more general problems we are working on where there's rotation and translation. So remember back when we had pure rotation. So for argument's sake, let's say it was rotating that way. We know now that any other point on the object, we can figure out its velocity from the fact that it will be moving perpendicular to the line connecting the two, and with the velocity that's proportional to the distance between them and that angular velocity there. In other words, the velocity of A equals omega. That's nothing new, but that's just from physics one. But we've maybe taken it a little bit farther in that we also know that any other point is going to be moving slower if it's nearer to that center or proportionally faster if it's farther by similar triangles. In fact, if we label these points what we're really saying is that the whole body, every part of that body, every line we can describe on it, every two points we could put on it are all moving with the same angular velocity and that that's proportional to their distance away from the center. So if we take that solve for omega that's the same for all of them, we have just where that rA and rB is the distance from the center of rotation. And we can even take it back off the other side, just continue this line straight through and we know then that the velocity of any other point is all found from the same similar triangle. We can do this any place we need. We can even do it some brand new place because they all have the same angular velocity. We've already used this several times when we looked at an object rolling without slipping, we know that the center is moving half the speed as a point on the opposite side at that instant. We've done that in a couple of problems. Is that right? Is that familiar? At that instant. In fact, since that point is sort of ephemeral in that a couple, an instant later that point doesn't even exist. We have a new center, a new contact point. This is really what you might call an instantaneous center. It's only the center of rotation for one instant. An instant later there's a new contact point and it's an instantaneous center. So we're going to use that idea now for our next approach to these general motion problems, the idea of an instantaneous center. The object that's in pure rotation, it's obvious not only is it an instantaneous center, it's a constant center. But for an object in general motion like a rolling wheel, this idea of instantaneous center can be quite advantageous for us if we can find it. Turns out it's not too big a deal. Any rigid body at any instant in time is rotating about an instant center somewhere. We just have to find it. So imagine we've got one point going in that velocity, some other point moving with that road. Just want to get a decent picture so things will work out right to start with. We'll say we've got some other point. It looks like something like that. We want to figure out something about the motion of that object at that time. We know that at any time any point is moving perpendicular to the center point. It's obvious if it's pinned at that point but it's also true if it's in general motion. So if we draw the line perpendicular to these velocities, we know the instant center must lie somewhere along that line because V, A, A is moving perpendicular to that line at that instant. The same is true for B. Those two cross is the instantaneous center and we know that those two lines connecting them always have the same omega as each other. If we can geometrically find where that point C is, thus get the distances AC and CB, then we can figure out the velocities. If we know the velocity, we can find out the angular speed of the body or whatever it is that we need to find for any point. You do a little sketch. It looks similar to this. It's bound to be that the instant center is. Some sketch like that, we just figure out where the instant center is. We'll see if we come up with about the same thing. Notice it does not depend at all on the magnitude of those two velocities. A location of the center doesn't. Well, it kind of does, I guess, because the farther they are from the center, the faster they're going to be moving. But in terms of just sketching it out now, in terms of where that center is, it doesn't matter. You're in technical free-in sketching, too. You don't need that kind of felt. Great, Jake. You did an awesome fool when you didn't hold the hand at all times. You got one of those, didn't you? Oh, yeah, definitely. All right. Very simple again. Perpendicular to the velocity, nothing else matters. And it's very easy, as you'll see in some of the pictures we're going to work on, that it's very easy, that it's distracted by other things in the diagram. Perpendicular to the velocity only. You should have gotten a center maybe somewhere down there. Notice, too, that it does not necessarily need to be on the body. It's just an instantaneous center. Nothing changes if I simply change the shape of the body to do that. It's still the instant center. So it need not exist on the body itself. Once we find that, you can see the direction of rotation. And then using the geometry there, hopefully, we can find the rotation. A question about the first line. How do you know what's going to rotate on a clockwise? That's the...on the first one. First one I wouldn't. I guess it couldn't move like that. The velocity arrows I picked, because these two arrows are moving towards each other, and they have a component such that the distance AB would shrink. So this one was just a bad sketch. It needed to move B out more this way. I guess, just a bad sketch. There. Now, we're rotating about there. That looks a little better. But, do we... So the original drawing would work if the two velocity vectors were really different sizes here. If, like, B-A was really big, B-B was really small. So you don't get any... No. Because the location of the center has nothing to do with the size of the velocities. It only has to do with their direction. And as I had that one originally, A moving this way, and B moving something like that, when you find the instantaneous center, there's no way a rigid body can be rotating about a single point at any instance such that they're doing this. Because this one has got to be going that way, and this one's got to be going that way. And that's not possible for a rigid body. They must have the same angular velocity. These lines must have the same angular velocity as each other, because they're on a rigid body. So that was, unfortunately, and I apologize, just a bad sketch. All right. Let's go back to the original problem we're doing today, see if we can get this to help us then. That was D. Now you know I didn't have a point C, because that's going to be the instant center. We know D has got to move like that, because it's down the slide. You know, B can only move like that, because arm A is pinned at the other end, where these two perpendiculars must cross. You've got to be careful with the geometry that it doesn't make you think it's someplace where it isn't. I don't have a protractor for this. I'm just sketching the board, so it can't come out in pretty different spots. So be careful with it. You know that's 45 degrees. That side's vertical, because that's perpendicular to a horizontal velocity. It may go down to A. It may not.  And we know this angle, or this one if you'd rather, is 30 degrees. And then somehow all these points come together. Remember we also had these, we had the distances, how long were those arms? 125 to 300. This was 125, 300. This is 125. Now I have that triangle there. I was doing omega inch per second it was. So both of those are also turning with that same speed. Because they're at that instant rotating about the same center. So if we could find out this distance, we know it's angular velocity, we can then find the velocity of D straight from that. Lobb signs, lob cosines. On this thing, sometimes the geometry is a little bit easier. Sometimes you need something like that. So you have two angles. Usually the lob signs I guess works better for that. You figure out what this angle is. Good triangle. There's two right triangles as well. Now whatever geometry works for you, as long as you get this distance cd. Because the velocity of D is equal to the angular velocity of, not a, cd times the distance between those two rcd. Omega cd we've already got. It's got to have the same angular velocity as bcd. So we only need to find that distance there. And you can do it by lob signs or lob, lax and lob cosines would be easier, probably. So what dc over the sine of the angle at corner b, what, 105 degrees? Is that just like that? Yeah, well this arm was at 60, so this angle must be 30. Because together they're 90. Remember, this is vertical. This is vertical and this is known to be 60. So that must be 30. It doesn't go directly to A, as a matter of fact. But it runs through that member of A. But, see A, this was, again, these are sketches on the fly. So A is really over here somewhere. D is not necessarily right above A. It just kind of looks like it in my drawing. But it's not. Vb must be perpendicular to that arm because it's pinned down at one end. To make this more to scale, that's 125, that could be. A is really much farther back down here. That's more what it looks like if it drops to scale. Because this is well over twice as long as that. So using the law of signs, which remember is the magnitude of one side over the angle opposite it. That ratio holds for any of the three sides in the diagram. See the importance of technical freehand sketching? You got to be really careful that your sketches don't tell you what answers there that isn't.  It's a lot different. It will originally be in the 4.64 meters per second and the negative 5. Yeah? That'll get 4.3 right. Well, let's check DC. So solving this, db is 125. We have sine b, which is 105 over sine 30. That's the side, the length of DC. What do you get? This angular velocity is not equal to this one. That's why this is in trouble. Because they're not on the same instant center. So those two together then represent with this point c, a separate rigid body. So actually this is omega db. Because it's the same angular velocity as that. So db we know, rbc we can find from the other sine 45. We already know the velocity of v. There's millimeters away when we have four readings per second. DC, what's this come out to be? It's 76. Sometimes when I break that up into two right triangles, I just add the extra moments. I get different answers. By breaking it here to get that distance? Yeah. Okay. I don't know how you're going to do that on this triangle. Because you don't know this distance or that distance. Oh yeah, because that's not today. I corrected that already. No, I know. That's the velocity here of this, which is this whole arm moving at four readings per second. That distance is 300 millimeters. So it's the product of those two. That's vb. Pictures can throw you off mightily. So let's be careful. Where did what come from? Let's try another one with a little more terrible drawing. Sorry about that. Make sure we did that right this time. 100 millimeters long. We will say c for the instant center, wherever that is. And that arm, bd, is rotating it two seconds per second in that direction. Find the velocity of a. Buy the method of instant center. Check it. That's okay. B and d have to be level with the midpoint. Remember, you're not paying the attention necessarily to any of the individual arms, other than to get the velocities. And use the velocities only to get the instant center. The mean itself. Look at the velocities when you find the instant center. What's point b going to do? Straight down because the other end is pinned. That's all it can do with that instance. So there's vb. In fact, we can figure out how big it is because we know the distance. We know the angular velocity. What's a going to do? It's got to go horizontal to the right because that's the way b is going to pull it and it's pinned at the other end too. What's your next step then? Perpendicular to what? The velocities. So here's one velocity, the perpendicular to that. So we know the instant center lies somewhere along there. Perpendicular to the other one and where they cross is the instant center. The velocity of b, how do you know that it's not perpendicular with a member of ab? Because the r and bd is pinned at the other end. But it's also pinned at ab? This is, these are separate rigid bodies. This rigid body is moving at both ends. This thing is in general motion. This is in pure rotation. So b cannot do anything other than follow in a circle around point d. Now don't make the mistake of thinking well if this thing kept running sooner or later it's not going to work. Because like I said, we're looking at these at a particular instant in time. Not as if they're going through an entire circular motion. Which they couldn't. Well maybe they could. Maybe when bd got all the way over here there's still enough length left in everything to reach general. But that's not the question. The question is at this instant at this instant find the velocity of a. Do you need any? Now with these velocities you know that this rigid body has some angular velocity like that. At that instant where ab and c make up an instantaneous rigid body. And that must be equal to points now make an instantaneous rigid body. This is the same sense of rotation that the piece ab itself would have. For bA you can solve it for omega if you need it. It's perpendicular to the velocity no matter what the arm you're doing. Very tempting to just make the velocity. Thanks. Nope. Let's see. Do you know what vb is? Or can you find it? We know what vb is because it's that angular velocity by that distance. So solving for vA. What's vb? 2 times 75 0.15 per second. RBC. BC is well if this is see this has got to be 50. How do you know that thing? Because I said that this was level with the midpoint. So now we have a triangle 50 there. How else do we know about it? Missing something? On the page. Numbers in? I think something's missing. Because all I have written down is that 50. I have written down. My solution, that's 175. Did I give you the distance between the two points? I think what I had was the length of that. I must have recopied my diagram and not drawn and written that down. So how long would that be then? Does that come out to be a nice round number? If you square that and square that and add them to square root that. Does that come out to be a nice round number? Nice round, doesn't it? So what's this angle? Is that nice round? We always have nice perfect round numbers in engineering. All angles are 45. All dimensions are multiples of 5. Yeah, go with one set of 5. I think it was just probably on the other diagram when I didn't really copy it. Did you contract how many mistakes of that today? I think I'm confident it was at the midpoint. We've got to see if we can do this on tape. For 3 meters per second then. The simple elegant method it presented. It's right. See now I've got to do this again next year. I've got to teach the hands again next year so I can fix this tape. Hold up, hold up. What's the omega equals the A of RAC? We have RAC. Omega is not even 2 meters per second. No, that's the angular speed of this arm. It's not the angular speed of what we really have is a rigid body that's like that at that instant where one side is the other arm whose angular velocity we don't know and made up of the connectors to the instant center. So that's a different angular velocity than the one that was given which is what, the E. I'll let you choose by whichever method you want. Here's the your get out of class question. Have a wheel rolling such that it's center 1.2 meters per second. Let me make sure that's right. Nothing else has been right today. Yeah, 1.2 meters per second. Here attached to it upon which is riding gear and rack system. Outer wheel is 150. Radius. Find three things. No meters. Meters. The size of a football field. A football field and a half. I want the next club to make that for extra credit. Find B of the rack and the angular of the wheel velocity of point D level with the center. And you can do by whatever method you want. Instantaneous center relative velocity or, I don't know, any other thing. The velocity of the wheel or in other words the center of the wheel. If that was on an axle attached to a cart or something, that's the velocity. Is there an instant center here? There always is. Every rigid body has an instant center at any instant. Is there one here? Talk about that being an instant center. Anyway, plus you know that the center has got to go level with the ground. This upper rack has also got to go level with the ground. And so if we draw perpendicular to the two of those they line right up somewhere on that line has got to be the velocity and we've already done that type of problem here. And then B, I'm sorry, D must be perpendicular to that one. And notice J sits that distance is not the same as that distance. That velocity can't be the same as that velocity. Point C at A in the rack B. You can find out what the angular speed is and then you know that ratio is the same for any other object at that instant. Velocity for the entire rigid body is the same. Yes, because they're all in the same body. All of those points are rigid bodies on the wheel so all of them must have the same angular velocity. The angular velocity isn't the same when you go from that to some other rigid body. For example, the rack itself is a rigid body and it has a completely different angular velocity. In fact, it's zero. Any instant on the well, any object on the rigid body all have the same angular velocity to any point, not just C, but to any point. Because the whole wheel has that same angular velocity. Now if they're slipping that'd be all together different. Then point C would have its own velocity that would be at the rigid somewhere else. Yep. Velocity at D. Yep, that's right. So you get it going early. How's that? Hold on, get moving. I'm just sticking away. To make sure you label that. That's two. Two meters per second. Omega is eight. Eight gradients per second. Yep. Always got it.


I have a couple of shapes. And I want you to start talking to each other about what they have in common, how we could sort them. Go ahead. Sort them by how many parallel edges they have. I could also sort them by how many right angles they have or a keen angles. What else? Sort them by size. What do you mean size? Like if one's really small and one is really big then you can put the small ones and the big ones in different files. Can you get your hands in here and start doing that? And why don't you talk about what you see so that other people can add? Yeah, there are. Like this one, they're like the same shape but this one's bigger and that one's like fatter but smaller-ish. So can we make some groups? Shay, what kind of, what do you have over here? Trapezoids. Oh, how do you know that they're trapezoids? This is a square because they have one set of parallel lines and then the others will eventually cross. Great, and what's that math word that we use for cross? Intersect. Intersect, great. So do you agree with Shay that these shapes have a name and that that name is? Trapezoid. Great, so let me find in here my label that says trapezoid. All right, so we have one group of shapes. Are there others? Yeah, we made a rectangle group and we made a parallel, yeah, a parallel group. We also made a square group. So I can tell that these shapes are different but can you use words to tell me what makes them different? They are different sizes. So let's look at like this group and this group. They're different. What is different about them? So can you jump in? Squares have all right angles and parallelograms have two acute angles and two obtuse angles. Oh, so Sadie's giving me some names here. So what was that name that we called these shapes? Squares. Squares and they're squares because they have four angles. Four 90 degree angles. And all their sides are the same length. And all their sides are the same length. Wait a minute, what about this one? Who can tell me what makes these two quadrilaterals parallelograms? Shay, jump in. All the sides are parallel because these could go like this and these could go like that. So if we're talking about pairs of parallel lines who can tell me a little bit more about parallelograms? Well, these two are pairs and these two are pairs but with this, this wouldn't be a parallelogram because it only has one pair but these has two pairs of parallel side. Okay, so I see now. So we have two pairs of parallel lines. That's what makes it a parallelogram. And can we attach a name to this shape? Somebody. A rectangle. And what are the attributes of a rectangle? Two sides are one length and the other two sides are like a small length. So it's like a longer shape but it's not as like tall up and down but it goes farther that way and it's made up of four right angles. Great, anybody else have anything to add? Because I see some parallel lines. Does anyone notice some parallel lines? Sadie, jump in. It has two sets of parallel lines. Oh my goodness. So do rectangles and parallelograms have something in common? What do you think, Shai? They're both parallelograms. Huh, that's really interesting that a rectangle can be both a rectangle and a parallelogram. Do you agree? Yeah. But I have a question. If a rectangle can be a parallelogram why can't a square or can't it? Can I move these groups here? What do you think? What makes a parallelogram a parallelogram? Jump in. It has two sets of parallel lines. So do squares have two pairs of parallel lines? Yeah. So can squares also be parallelograms? Wow, Josie. Rectangles are kind of like stretched out squares. And I think that's what Elise was talking about. It's almost like you stretch one of the sides, right? And if you were to smush it together, it would make a square. All right, questions? Elise? The trapezoid is like in its own group, but like these are related. I'm wondering if the trapezoid is somehow related. Hmm, well, what is the attribute that makes a trapezoid, a trapezoid? Jump in. There's two lines that would intersect, and then there's one pair of parallel lines. Yeah, and so what's different about a trapezoid at any parallelogram? What's different? Only has one pair of parallel lines, but parallelograms have two sets of parallel lines. Yeah, so I agree with you, Elise, that these three shapes are related, and these three quadrilaterals are related, and that the trapezoid doesn't quite fit in with that group because it only has the one pair.


And how do you know? What takes longer and how do you know? Oh, you got put on the spot, Emily. What takes longer and how do you know? I think it's maybe four, six, because if one half of a minute equals 30 minutes, probably. Refraise what you're thinking. One half of a minute equals 30 minutes? One half of a minute equals 30 seconds, because you're saying half of a minute and a minute is 60 seconds, and half of 60 is 30. So I think four, six is more than one half, because it could be more seconds than 30 seconds. How is Emily using her knowledge of fractions to correctly state that? How is she using her knowledge of fractions, and what she knows about benchmark fractions, and where fractions are in terms of greater than certain benchmarks or less than certain benchmarks? Gerilyn, what do you think? So in other words, how does she know that four, six is greater than one half, just looking solely? Let's say we didn't even know how many seconds equals a minute. Just looking at those fractions, how do you know that four, six is greater? I think that four, six is greater, just like Emily said, because if you divide six times 60, which is the seconds, it'll give you about like 10, like 10. Let's forget about division, okay? Let's focus on our fractional knowledge. What do you know about halves, and what do you notice about four, six? That four, six is greater than a half, because when you simplify the four, six, it'll give you two thirds, and two thirds is greater than a half. Very good. But what else do we know about that six, and how is it important to really analyze that six? Gabby? One, four, six is greater than a half, because a half of six is three, and the fraction will be three over six, and this is one more than a half. Very good. So what Gabby knows is this represents one half. One half represents one half. She knows that four, six is greater than half, because what is half of six? Three, but do we have three parts of that six? We have four, six, all right? So we have more than that half.


Block of allies of Russia and China in Latin America will reduce the influence of the United States. Experts from Latin American countries comment on the loud statement of Venezuelan President Nicolás Maduro, who recently spoke at the National Assembly of the country. Maduro proposed to create a political block of allies of Russia and China with the participation of Latin American states. Maduro is confident that such a political block could become a new pole of power. This community would share the common goals that our elder brother, President Xi Jinping speaks of. Humanity united by a common destiny. Our building, that multi-polar and multi-centric world that our older brother, President Vladimir Putin is talking about, Maduro said. These statements caused different reactions in the expert community. Although Maduro has already managed to present the idea of a political block to the presidents of several countries in the region, we are talking about Argentina, Brazil, Chile, Colombia, etc. The proposal to create a new association is, to some extent, a continuation of the idea of Brazilian President Lula during his first presidential mandate to create a military block of a united South America, although perhaps Maduro sees the transformation of this association into a military political union in the future. In Brazil, there were brief media responses to Maduro's proposal. It should be noted that media sympathetic to the right and Jair Bolsonaro in particular gave derogatory characteristics of the idea of a new block as complete nonsense. An idea absolutely unnecessary for Brazil, etc. But in Brazil, there is another point of view, namely that such an alliance of an equal footing with Russia and China will enable Brazil not only to strengthen its regional status, but also to join the circle of world powers. Brazilian political scientist Pavel Gras, an expert at Tropical BRI CSlus Consulting Company, told EAD Daily, in turn, another well-known Brazilian expert and public figure, Enrique Dominguez, special secretary for Latin America of the BRI CS IMF, is sure that the statement of President Nicolás Maduro on the proposal to create a political block of Latin American countries with the aim of collectively joining the Chinese Russian efforts to build a new, multi-popular world of universal prosperity meets the historical needs of the region. However, the full integration of the Latin American region is not in the interests of the United States. In this case, it will be more difficult for the United States to continue to exert direct influence on the South American continent. That is why the constant interventions, destabilizations, sanctions provoked by the U.S. in Latin America harm the development and deepening of Latin regional integration through existing organizations. Therefore, reproachment with China and Russia, as suggested by the Venezuelan president, could be a good tactical path to secure a future with less U.S. interference in Latin American affairs, and also to consolidate Latin America as one of the poles of power in the new, multi-polar world that is beginning to take shape in the coming years.


Hey everyone, Dylan Schumacher, Citadel Defense, and today we are going to paint this backpack. This is a 511 Rush 12 backpack, had for a couple years. Really like it. However, I bought it in black several years ago. And when I bought it in black, I bought it because, you know, you buy everything in black, right? That's kind of your tactical guy, all your stuff ends up being black. But here's the thing about black. At night, it actually sticks out. I know that's very counterintuitive, but this was driven home to me when I was at a night course. And I was wearing a black jacket just because I was cold. And we were out in the desert. And they did demonstration. It was dark out. The stars were out. And the moon was, it wasn't a full moon by any stretch. It was maybe like a quarter, maybe half, something like that. And they had me and another guy who was in a camel, like multi-cam, stand out about, I don't know, 20, 30 yards away. And I was easily visible in my black coat. And the gentleman in multi-cam couldn't see him. It was really hard. And that has to do with the way that your eyes see hue in different colors, science and shit, right? So anyways, I want to paint this one reason for that. And the second reason is that, you know, black doesn't stick out or doesn't blend well in like a wooded environment or anything like that, either. So I'm going to try to paint this pack. Now, I've never painted anything nylon before. I painted a gun before, but I haven't painted anything nylon. So I'm assuming it's going to soak up a lot of paint. What we're going to do here is we're going to tape off the Velcro fields because I do want to maintain those. I'd like to keep those. And I might put just a thin line of tape here on this top zipper and maybe this zipper right here. The rest of it, I'm just going to leave. I'm just going to leave the rain flaps over the zipper, let them do their job. And that should protect those just fine. So we're going to paint this. We'll be kind of experimenting to see how it turns out. And if it's something you should even bother considering doing or not on your backpack, because I'm guessing you probably have a couple black backpacks and maybe you want to paint them to actually be able to use them. So let's paint it. Let's see how it turns out. And we'll go from there. Okay, so we're going to go with the backpack here. We're going to start with a green. Oh, green didn't really seem to do much on this thing. So I'm going to try a, what is this even thing? Some kind of light tan deal. It's basically the color of this cap. And we'll see if that takes the color a little better. I seem to have better luck with this on the plate carrier, which is also black nylon. So hopefully the tan will take a lot better to this backpack than the green did, because the green basically did nothing so far. Can't really tell much. Not that much left on this can. I think I'm just going to use the rest of what's in here. This is not turning out how I originally envisioned, but I'll be honest. I kind of like it. It's kind of turning into this dirt, ugly, hideous color that doesn't look good at all. However, I think we'll blend very well in a wooded environment. So I'm going to finish off what I have left in this can. And then I'll let it dry probably overnight here, and then I'll try to hit it with some green tomorrow, and we'll see how that turns out. That's it. Let's see how it turns out. Okay. So I let it dry overnight here, and we kind of got this dirty can thing going on. So I'm out of tan, and I'm not going to go by more. So I have some green left. So I'm going to try to give it some streaking here, and we'll just kind of see how that turns out, and probably just going to roll with that.  That's kind of the color it would have. Like it's really dirty. So I'm just going to give it some green streaks, and then we'll let it dry, and we'll see how that turns out, because I think that's going to be about it. Okay. We'll let that dry, see what happens. So here it is. Here's the final product. Kind of looks like dirt. I can bury it in the backyard for a week. When I showed it to my wife, she told me that I ruined a perfectly nice backpack. So take that for what you want. I think overall it's going to blend pretty well, and because I use the same colors and kind of the same streaking, I do end up having a matching set with my plate carrier. So that's kind of fun. But overall, so point being what I've learned in this experiment is one nylon soaks up a ton of paint. So you need a lot of paint. I did preserve the Velcro fields, which maybe I shouldn't have. Maybe that's going to stick out too much, and maybe in a bit I'll end up painting those down. But I did want to still be able to put patches there, mostly for identification purposes, and to mark this bag, you know, for what it's for. I didn't really spend a lot of time putting it on the back, but I do want to try to get the shoulder pads a bit and the buckles and stuff like that. So we'll see. I'll use it. I'll run it for a bit and see how it turns out. But this is the final product.  And you can have a nice dirt backpack just like me. So this was an experiment to kind of see how it would go. Overall, I think I'm pretty happy with the results of it. I do think it's going to blend a lot better. It'll blend a lot better than black and it'll stick out much less. It'll be much less noticeable, which I'm happy for in wooded environments, which here in Minnesota is about four to six months out of the year kind of depending. So that's a big deal. Overall, it does look dirty. That's the downside, but what can you do about that? So that is my DIY camouflage job. I'll let the results speak for themselves. I won't sit here and rant at you. Do brave deeds and endure.


The topic we are going to talk now is the need of the mental health professionals in legal system. Since we know that at times we heard in forensic psychology there comes the stage when we have to have align the need of the mental health professional with the legal system. Mental health and behavioral social professionals have increasingly found themselves involved with the legal system as being expert and as being dependent. So their needs are very much present in different scenarios which we will talk about now. Forensic psychologies and emerging field and forensic clinicians have important role as experts, witness or consultants for many different type of legal matters. Now you see while conducting forensic mental health assessment which is very much present, the practitioner must be especially careful while trading into legal system as they are about to enter philosophically aligned territory because there are some complications of legal system which as long as a forensic psychologist doesn't study properly it becomes very difficult to intervene into them and you may not be able to understand the legal system as long as as a forensic psychologist you don't study those legal complications you don't develop an acquaintance with it and then you can see that how you can play your professionally equipped role into that system. Legal lands may arrive for mental health evaluation along at least three different roles. Now those people who are a part of any legal case can come from those three reasons with their cases to mental health professionals. First, some legitants may come for evaluation under a court who is sent to court and he says that you should see for example to assess the defendant's competence to stand trial or often guidance in a child custody case. First of all, it seems to be simple but rather it's not that simple to determine that either a person is mentally able enough to do anything or not or the person who has come for a case is mentally mentally insane or not. Or if a child's custody case alleges that this parent is not mentally fit to take care of a child then in that case it may be necessary to assess and see the mental health status that either he is mentally able enough to do a child care or not.  Sometimes to save yourself from some situation to take this claim that I am not mentally well that's why I have committed to describe. So this can be used for your own defense. Valuation related to potential insanity defense. This can describe insanity defense in such a way that a lawyer says that you have this provision in law that if you could do this crime in that form then you could have said that you are mentally stable. So in those situations people come to get assessment because they need that insanity defense. Then third, the parties may agree to have a legitimate evaluated in the absence of a court order. For example, in many civil and in many criminal cases the parties understand that the opposing side has a right to an evaluation conducted by their own experts and informally agree to do so. Because if you have a case in which two parties and one of them has made an assessment then the other party has a right that they can go for their own assessment. So basically to give someone a counter narrative to prove that your assessment is not correct then the other party can also get an assessment out of the court. So these are the basic three types of the reasons because of them the legally related cases can come to the psychologist for an assessment but for all of these it's very important that the person should have a complete knowledge of legal procedures and he should must have training in forensic psychology.
