Rigid Body Kinematics: Relative Velocity & Acceleration | Instantaneous Center of Zero Velocity 

Whatever they are paying this man it's not enough. My professor breezed through the intro to this chapter and just dived into the practice problems. This was amazing. Thank you so much.

Sir you are the best of the best , from South Africa. You changed my life and you are an awesome mentor, I attribute all my distinctions, 9 and counting in mechanical engineering to you .

Why am I just now finding out about this channel!? Awesome video! I have a quiz on this tomorrow and this just might have saved me!

I'm glad I found this channel. It's been so hard to find videos on dynamics from native English speakers. Thanks! the video was very helpful.

Thank you a lot for this wonderful explanation. You have covered an extremely large variety of topics, but while searching for the topics, your video don't come at first when it's the most understandable & most wonderful lecture throughout the internet. I think you should start making playlists of videos of different topics and you will rock.

By far the best teacher. Why? You are the only one I come across ( maybe there are others that I don't know of ) that give the time to the audience of thinking about the concepts before moving . Mostly that is not the case end teachers just do bla bla bla senselessly even the topic is relatively complex to grasp in short time. Simply it has too many elements to memorize or combinations. Thanks.

Absolutely killed this lecture man! Explained this concept so much better than any other channel I've seen so far. Thank you so much!

1:12:35 This video has been very thorough and helpful. I will say, though, that our vector equation is actually in three dimensions, so we can solve and simplify both sides of the equation into single vectors, then equate their i, j and k components to obtain our system of 3 equations to solve for our 3 unknowns. At least, that's the way our book is doing it. However, reducing it to 2 unknowns is probably faster.

If you found this video useful, consider helping me upgrade the old tablet PC I use to create these videos! Thanks! www.gofundme.com/help-replace-my-2011-tablet-pc

I'm usually the "figure it out as you go" type of person, but I couldn't figure this out as I did practice problems. Finally, after ~6 hrs of studying, I found this vid, and it was more helpful than those six hours. Appreciate the help!! Changing my study process as we speak (:

Thank you! I tend to use this form of writing

My PE test is tomorrow actually. I was looking for a last minute refresher on this topic and remembered your videos. I've always enjoyed your teaching style. I greatly appreciate this content. Hope your doing well!

You have a great teaching style and this video has been incredibly helpful. Thank you

Great and very helpful video! So, I have a question I hope you can help with and it's been bugging me for ages! Torque produces angular acceleration for a given moment of inertia, and when the torques on a system balance, you have no net acceleration and a constant angular velocity of that system. Great! I assume the reason motors and any other object subjected to torque doesn't just constantly accelerate is because reactive torques in the system grow as the object increases its speed until equilibrium is met - akin to terminal velocity? What would those 'growing' reactive torques be? I can only think of drag, but I assume there must be others that contribute more and i assume, most if not all are some functions of velocity? For a practical application, say in sizing a motor to drive a belt system that has a design constraint of a set velocity, the way I would do it at the moment would be to balance torques at the point in time where the rotational speed is exactly what I want? If I assume reactive torques increase from zero rotational speed, then they should then balance my driving torque at the correct speed? Not sure if you can clear it up for me, but worth a shot - I am probably not explaining myself very well.

Best video I've ever seen on these chapters

loved the explanation! got exam for this tmr! THANK YOU SO MUCH

Great Video! Loved your teaching methodology!! Thanks a lot for making this video. ☺️

Thanks for classes sir, very helpfull!

In my class for relative motion equations the professor taught us to draw vector components for each unknown in the equation. And instead of using the cross product in our formula we write relative velocity for one point relative to another and solve by drawing a RAFA stick. But I like the information from this video

Amazing video! Very informative and it helped me a ton !!

Thanks sir. I really really found this helpful.

My doubt for instantaneous centre is no more. Thanx sir

God bless that i found your channel sir! Thanks a lot! Very-very useful! Keep up the good work! +1sub

Thank you so much

Thanks you so much!

why i dont have to say angular velocity around a point. Is angular velocity about any parallel axist to a rigid body same. I mean, Wab=Wba? I have been stuck on this doubt since long ago. please answer.

Thanks Prof

Such a great VIDEO!

thank you sir

Hello sir. Can any of the acceleration related questions be solved using the Instantaneous Center of Zero Velocity ?

is in the equation a there is something wrong?

God

lol are you talking in front of a class? they arent saying anything im sorry lol
