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 .
Glad to have you aboard! I'm glad the video was useful! I grew up a Californian, so it has taken me a few years to perfect the drawl well enough to fit in down here :) In case you haven't seen them yet and might be interested, here are some of my playlists: ENGR122 (Statics & Engr Econ Intros): ru-vid.com/group/PL1IHA35xY5H52IKu6TVfFW-BDqAt_aZyg ENGR220 (Statics & Mech of Mat): ru-vid.com/group/PL1IHA35xY5H5sjfjibqn_XFFxk3-pFiaX MEMT203 (Dynamics): ru-vid.com/group/PL1IHA35xY5H6G64khh8fcNkjVJDGMqrHo MEEN361 (Adv.

Best of luck in your studies!
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.
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 (:
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!
Thank you for the affirmation! I'm glad you found it helpful!

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.
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
@@TheBomPE There's 2 professors that teach the class and I can't find anywhere online where people use the same method. I think they try to avoid vector notation
I'm glad I could help! I love instantaneous centers!

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.

Not really. Some people use an instantaneous center of acceleration, but I have not personally found that method to streamline many problems. Instantaneous center for velocities, however, is a technique I use frequently. Thanks for watching!
