Hello everyone, Myself Sachin Rathod working as assistant professor in mechanical engineering department from Walsh Instruct Technology, Solar Pood. Today we will discuss the selection of the belt part 10 under the subject of machine design one. The learning outcome of this session is the students will able to design the V belt from the manufacturing catalog. So, just we will consider one problem statement from which we will get the design procedure how to select the V belt from the manufacturing data book. So, this is a problem statement. A V belt is required for 15 kilowatt power having the speed of 1440 rpm electric motor which drives a centrifugal pump running at 360 rpm for a service of 24 hours per day means we have to convert the speed from 1440 rpm to 360 rpm on which the centrifugal pump is mounted. So, here the application is centrifugal, we have to run the centrifugal pump from the electric motor. From space considerations, the center distance should be approximately 1 meter, the distance between input shaft and the output shaft that is nothing but the distance between electric motor shaft and the centrifugal pump shaft is 1 meter. So, we have to determine the belt specification number of the belt, the correct center distance and the pulley diameter. So, these are the given data 15 kilowatt power speed of the input and the output shaft that given us the service we have to use for the 24 hours per day centrifugal pump and the center distance is 1000 mm. So, the step number 1 is to determine the correction factor according to the service that is F A from the design data book. So, from these tables we have to find out the service factory F A. So, as they had given us the 5 kilowatt powers the speed of the input shaft is 1440 that is a faster pulley and the fan service is 24 hours per day. So, according to this we have to find out the service factory F A. So, we have to run the centrifugal pump and it is running for the 24 hours per day. So, you have chosen the factor service factory is 1.3. So, the second step we have to find out the design power, design power is calculated by using the equation design power is equal to F A into transmitted power. So, the F A is 1.3 and the transmitted power. So, step number 1 determine the correction factor according to the service from the table. From which we have to find out the service factory F A. So, this is a given data on the power is 15 just correct that the power is 15 the input speed is 1440 rpm and the fan service is 24 hours per day. So, by considering the 50 kilowatts so, it comes over 7.5 so, it comes under the medium duty and the service we have to use for 24 hours per day. So, we can see like the service factor is 1.3. So, in the step number 2 find out the design power. Design power for the V-belt we can calculate by using the equation F A into transmitted power. So, transmitted power is 15 into the service factor is 1.3. So, you are getting the design power is 19.5 kilowatt. Step number 3 determine the cross section of the belt based on the design power and the high speed of the shaft in the rpm from the table. So, this is a table from which we have to select the proper type of the cross section of the belt. So, in these tables we have observed that there are the 5 types of the belts are available A, B, C, D and E. So, based on the high speed and the design power we have to select proper cross section of the belt. So, the horizontal line on the horizontal axis indicating the power and the vertical line indicating the speed of the faster pulley. So, as the design power is 19.5 kilowatt. So, this is a line for the horizontal line indicating the design power just I have drawn one line which is passing from 19.5 and the speed of the faster pulley is 1440 rpm just I have drawn the horizontal line. So, intersecting is at this junction. So, this is we have to use the B cross section belt. So, which is ranging from this line. So, I have selected the cross section of the belt is B type. So, the cross section of V belt is B type. So, in the next steps the dimension of the cross section standard cross section belt that is a we have chosen as a B belt. So, the pitch width, nominal width and the nominal heights are we have to take from this table. Also, the recommended minimum pitch diameter of the pulley is 200 mm and the permissible minimum pitch diameter of the pulley is 125. So, you can select the value of the diameter of the smaller pulley which is ranging in between these two or you can select 125 or 200 as a diameter of the smaller pulley. So, for the B section belts the value is ranging from these two value. So, you can consider the diameter of the smaller pulley as 200 mm. Now, in the next steps you have to calculate the diameter of the larger pulley by knowing the equations n 1 d is equal to n 2 d. So, these equations we are getting from the relation the speed of the shaft and the diameter of the pulley that speed is inversely proportional to the diameter therefore we are getting n 1 by n 2 is equal to capital D by small d. So, from that equations we are getting this. So, just put the value of n 1, n 2 and small d you will get the value of capital D. So, capital D is equal to 800 mm. So, from the standard data books you have to check out this data. So, we have selected the B belt 800 is available. So, you can select the value of the capital D is 800 mm. So, in the step number 5 calculate the pitch length of the belt. So, in the step number 5 calculate the pitch length of the belt. So, pitch length is calculated by using this equation as the data we are knowing capital D small d and c put that value you will get the length of the belt. So, we have to check out the standard pitch length from this table. So, for B section belt you can select the pitch length of the belt is 3600 mm. In the step number 7 find out the correct central distance c by considering the standard pitch length. So, you can pause this video and you can think about this why it is necessary to find out again the center distance that is called as a corrected center distance. So, you can think about this. So, if you put this value in that equations you will get the corrected center distance is 968.118 mm. In the step number 8 determine the correction factor for the belt pitch length fc from the given manufacturing data. So, this is a table from which we have to calculate the correction factor fc. So, as we are using the B belt and the length of the belt is 3600. So, the correction factor fc is 1.10. So, I have selected fc is equal to 1.10. In the step number 9 calculate the angle of contact for the smaller pulley. So, by using this equation we have to calculate the wrap angle put the value of capital D small d and c you will get the wrap angle alpha s is equal to 143.89 degree. So, you have to find out the arc of contact factor fd from the manufacturing data book. So, this is a table from the manufacturing data book calculate the value of fd. So, we are getting the value of the fd is 0.905 as the alpha s if you observe that alpha s which is ranging in between these two 142 and 145. So, the factor should be the in between these two value. So, you can consider the factor is 0.905. So, the step number 11 find the power rating of the belt that is a power transmitting capacity of the belt PR. So, as they are given us the speed of the faster pulley is 1440 rpm and the diameter of the smaller pulley is 200 rpm and the B section bed having the speed ratio is 4. So, speed ratio is nothing but the speed of the input shaft divided by speed of the output shaft we are getting as a 4. So, by using this data you have to find out the power rating. So, the speed of the faster shaft is 1440 rpm. So, we are getting the diameter of the smaller pulley is 200 mm. So, it is the value is 5.90. Again, we have to consider the speed ratio is a 4. So, the speed ratio is 2 and over the value is 0.46. So, 5.90 plus 0.46, 5.90 plus 0.46 you will get the power rating as 6.36 kilowatt. So, in the last step, step number 12, determine the number of the belt. So, the number of the belts we are getting by using this equation. So, just put this value you will get number of the belt is 3.07. So, you can take the whole number as 3 belts. So, the 3 belts we required for that power transmission. So, you have the final design solution will be obtained as the diameter of the pulley small d is equal to 200 mm, diameter of the larger pulley is 800 mm, diameter or the belt specification is B3600 LP V belt. Number of belt required is 3, the center distance is 968.118 mm. I have taken this reference as a design of machine element book which is author having VB Bhandari. Thank you.

Okay, here's your lesson on easy blues, the first guitar song to learn. Now, we've talked a little bit about the tab, and if you notice that the first line has the same four notes repeated four times. So we're playing a pattern four times over. If you look at the second line, you're going to notice that it's the same pattern only one string higher on the guitar. Changes a little bit in the third line, and then finally goes back to a very similar pattern to the beginning. So there really are a lot of patterns that we're going to see. We're going to play all of these notes with your thumb on your right hand plucking the strings, and it's going to sound like this. You're going to notice that I played it slow and very steady. To me, steady is much more important than fast. If you decide you want to play it fast, make sure you don't put a hesitation between each group of four. Let me play it a little faster so you can hear it that way as well.


Hey, this is Brett the Ford guy and today I'm going to show you how to get your door code off of your 2005 2006 and 2007 Ford 500 cars this might work for the 0809 tourists as well. I'm not able to verify that but Maybe try it on there. What we're going to do is we're going to find the door code for This code right here if you don't have the card and you weren't given it and you just don't know it There's a easy way to find it. It's relatively easy You're going to need three tools for this. You're going to need a ratchet You're going to need a 10 millimeter socket and then you're going to need a cell phone with a camera video camera and a Flashlight on it. We're going to use the camera that we're doing the video with for the example here But it's really quite easy. You take your socket and your ratchet and there is a fuse box Underneath here looks like that and you're going to remove this bolt or nut right here I already have it loosened but you can get the idea loosen it with that take that off Like so that'll fall down You can put your socket down and then this will pull forward now what you're going to want to do is you're going to want to take your cell phone and aim it right behind This bracket here, and you'll be able to see your door code on here. I'm going to tilt the camera up like that We're going to put it behind here with a camera And there's a sticker Right there, and that's going to have your door code on it So that is your master code For this vehicle you can put that nut back on and tighten it down and then you can program your door code and program your own door code and We actually did a video on how to program your own door code and that's in the upper left hand part of the screen More door code location finds in the upper right hand part of your screen if you want to subscribe to our channel in the lower left hand part of the screen and In the lower right hand part a relevant video to this one click those check us out remember to like subscribe and share and If I helped you out give me a shout in the comments. Thanks again for checking out the video


How was everybody doing welcome back to my channel this week my client is flying in from Canada to get a cover up done And the person that I'm tattooing is Caleb better known as Moose I don't know if you guys remember but about six to seven years ago people started getting a forest around the wrist Tattooed with the trees going up the forum, and it became very popular about six seven years ago And if you have one of these tattoos, let me know if you still like it as much as you did when you first got it done Or if you're slowly starting to not like it anymore, and my client is no longer happy with it So we're gonna cover it up with something insane So with that being said let's get this day started. Let's go Hello the subject this professional gamer with a horrible half-sleeve in need of a miracle. Currently. I travel the world to play video games What he's living your dream? What for a long time Kevin was considering becoming a professional gamer No Not a gamer like I only play rock-a-league. That's it Currently I travel the world to play video games, and it's pretty cool except for one problem This tattoo on my right arm as for the design of the tattoo I think giving you full freedom to make something we will both be extremely happy with is it is a play. Oh You're holding it backwards Oh It's backwards I'll take it So what are you from where you coming from? Ontario, Canada Is it cold over there right now?  Did you bring sweaters? I brought one one hoodie, but only like sweatpants I see I see what you had and I was like he needs my help So you said you're a gamer.  Yeah, that's insane. I mean it's fun. It's better than anything else I would be doing, you know, so Playing video games against.  I've been really chill. Oh wow people that slam their desk and stuff But ever since I switched to this game Valorant It's starting to come out of me like this game does something else to me I've had some slams What places have you traveled to? So like a lot of places in America.  What are we doing? Why am I tattooing? I shoot. I'm gonna take a year off Practice after this It's like do my tattoo first. All right, so we got the outer form ready.  All right my guy. I'll see you tomorrow much Rest and drink a lot of water. I will drink a lot of water.  I'm gonna have to Bump up the contrast and I don't want that because the face is very very bright So I'm gonna do I'm gonna apply the stencil where the facelands go right here That's your arm as much as you can. There you go. Don't think about it too much. It's kind of glanced at it and Let it happen the face landed Nice Yes I don't know the lyrics Well, you're gonna go home speak in Spanish, bro You you know how to speak two languages Oh, you know French crazy There's a good spot to explain a couple things so there's two trees here and There is a lot of open gaps I can easily just go and Start adding texture across the whole entire thing From here to here to here to here, but we also got to make sure that we keep in mind that It doesn't just look super dark So I'm using my seven round liner right now with the voltage of a 5.0 and I'm gonna be using my medium tone here my medium gray and what I'm gonna do is Make this into a glare of the helmet. It's not on my reference But I definitely need some sort of glare on the helmet to bring it back to or to make it look brighter So that's why I'm gonna make this little gap here into a glare Go in dark here so I can fade it out So medium gray Start adding textures and little details like this is what really makes a Piece come together and when it comes down to doing, you know Cover-ups you just got a there's some areas. I just got to improvise But you have to be a hundred percent sure about what you're doing And then once you start creating that glare start, you know going inside the glare and adding texture Little scribbles dots excess Because it can't be just blank, you know, you got to also continue the same pattern To make it look like one No, I'm about a tattoo with the beat bro I'm gonna be doing extra texture with this song, bro And just like that you start creating that glare Start build just build it up slowly. I Definitely for me was a It is something that I usually like to do. I can't concentrate right now bro with this song. I Can't even explain nothing I Wonder I wonder if my my other clients get nervous when I say, you know, all you got to do is just improvise see what happens You don't get nervous Those are facts bro, you had trees is it perfect a glow see it I mean I'm not keep adding more texture, but you get the idea of what I'm trying to do is adding Making this dig layer High contrast here, and then do the same thing on here So it looks even across the whole helmet and you don't have to go solid black across the whole entire thing because if you have a You know if you're doing a cover-up and everything looks black, then what's the point? You know you got to separate the contrast the highlights and make it let the tattoo breathe If it's not breathing it's not gonna be legible. Who started calling you moose It's just like the name I chose like I needed to choose a name and appropriate So it was like this is it. I don't know it just worked. I make a big play they all go the moose is loose That's dope the moose is loose That sounds something One of like my best Clips ever was like we're at a big tournament It was called the minor, but it leads up to like the major which is pretty much like the Super Bowl of Counter Shrek And if you make the major you get like a little sticker with your signature in the game that people can put on their guns And you like get money from it. So you're pretty much like a mortalized within the game And so we're playing the minor we're playing like the best team in North America the best team at the Or not the best team in North America, but the team that was favorited to win the minor and like top three North America and we're third map and There's like a 1v5 and I won it and my my team like went crazy Now I was chill like in the clip you can see I don't even move My teammates are going crazy around here. Yeah, I was just like excited for tomorrow. Let's go. How you feeling, bro? Too big as apples in here Oh my god Right where I pictured it perfect size Parties and Jesus juice like always Sass we have the rest of the forum here that we're gonna complete because he has a flight to catch tonight at What time is it right now like nine? Yeah, 925. Oh, yeah, we got a lot of time. So my goal for this then so is to make sure that The eye here Goes right through the middle. So this tree here is gonna go through the middle of The octopus here. I feel like I say you're going every time I say octopus Octopus octopus Octopus, yeah Octopus, yeah octopus Squid I feel like I can say squid better than octopus. I gotta get comfortable.  Yeah, I can be just sasa sauce Some of the guns in this game like you can buy like different skins and stuff and Some of the guns make different noises. So maybe they'll add that to the game Yeah, sound by mr. It's to Have you highlighting your conscious in the right spot? Just look it. Just look at how much of a difference is gonna make from it all to this eye on this act of Octopus The square there has to be another way to say octopus, bro, like oh Wait, I think I just said it right without thinking about it octopus Ah Octopus Look at the difference that this is gonna make so we have the eye here. I did a pretty simple stencil Heavy contrast right under the eyelid happy black Because this is a cover up you gotta take advantage of those open space or those negative or blank areas of the skin happy black So you got to go in there. Don't be scared. I didn't texture at the end of that Shout out under the lid it's gonna make it happen And make a few adjustments as you're tattooing if you feel like you can move it a couple millimeters do it If it's gonna land on the spot that you wanted to land Now on my reference. It looks a little dark. I'm gonna see if I can put a picture around here to use it as a reference on My reference looks completely black, but I am gonna add Texture I'm gonna enhance the texture under the this eyelid I'm using a 14 round liner with the same voltage that I use in every tattoo in every piece in every placement It doesn't matter what I'm doing five round or a five point zero voltage So using five point zero voltage with the 14 round liner and just do textures If you're new to my channel, if you look at all my videos This technique is something that I've been using for years now And it makes me really happy to see that other artists are benefiting benefiting benefiting Something's wrong with my vocabulary today, bro It makes me happy to see the other artists I are I'm help Lord Jesus my god, I should just stick to tattooing bro Almost I'm talking now Yeah, a lot of our artists are sending me their tattoos showing me that the technique worked for them and that makes me really really happy So give it a try and send me a message on Instagram if you worked out for you But I highly recommend it. It's not an easy technique to To learn but once you learn it is definitely gonna help out It's definitely gonna elevate your game For me it's pretty much muscle memory at this point I'm able to do the textures that I need to do in one single stroke because of my my head movement muscle memory the pressure that I'm putting on the skin and The tones that I'm using I'm so comfortable with them that I'm able to just go in Single stroke and next thing you know, I have a lot of texture just like I just showed here So I'm gonna go in in here This little corner boom. So as you can see once I reach the end of the Drop shadow here under the eyelid. I'm just gonna slightly start doing little textures very Separated from each other that way. It's not as dark Now this is a little bit hard to explain for me, so I'm just gonna kind of Show what I'm doing and hopefully you can Kind of get an idea of what I'm doing because it is a little complicated to explain I wouldn't even know how to explain this part the best thing I can do to show you And I'm just using solid black right now. I'm not using any gray tones at the moment Just solid black. So now that I am looking at the whole thing. I'm like, okay now I'm able to see the shape of the eye. I really like the textures but before I continue adding more contrast I'm gonna go in into inside the eyeball and pack in those solid blacks because I want to make sure that I'm not going too dark and You know me just working on this area and not looking at the full picture What can happen is that once I'm done? I'm gonna be like damn it. I went too dark or I need more Contrast in it. So I'm just moving evenly I'm navigating that way. I Don't get lost in the contrast and highlights So I'm looking at the bigger picture the whole entire time. Wow, that was pretty smooth That was very satisfying Same thing here. Perfect. So now I'm gonna look at everything and Right now what I need is to keep adding texture here on the corner and I'm just using solid black. So I feel like I'm in a good spot. I'm gonna add a little bit more here Before I add my gray tones inside the eyeball I like to I'm what I'm doing in right now is I'm just kind of mapping it out and seeing how How it's gonna look with the great tones It's kind of like a little preview and I'm gonna look at the whole thing. All right, perfect now I'm ready to start adding the great tones texture texture I'm gonna make this the the brightest part of the eyeball right here because I definitely got it covered that up with some great tones and So I'm gonna make this the the glare I'ma go in and fade out That's a lot of explanation The whole thing having the trees finally After what like six years, right? It's been a while Honestly like to forget about when I got that so it's kind of like try to erase it from my mind But I'm honestly mind-blowing with how it came out. Like you went crazy I'm just happy. Like I didn't know what like what was possible with what I had already You know, like I don't know what's possible And like I never thought something like this would be possible. So It feels like honestly, I can't really put it into words. Like it feels like a long time coming and Like it's really it's crazy. It was my pleasure my guy. Thank you so much Get the moves going. Yeah, I'm down Hopefully soon. Yeah, I'll let you know, bro
