Lecture Series on Dynamics of Machines by Prof. Amitabha Ghosh Department of Mechanical Engineering IIT Kanpur For more details on NPTEL visit nptel.iitm.ac.in
In the first part of the video, the angular aceleration of de cilinder shoud't be w1x(w1+w2) taking in account that the absolut angular velocity of the cilinder is w1+w2??
That's a term which takes into effect the rotation of the coordinate system attached to the rotating body. He is saying that when both observers are watching a vector which changes, what they measure as the rate of change is the same once you add in the effect of the rotating reference frame.
His handwriting should be visible in an art museum somewhere.
I agree with you whole-heartedly. Those drawings ..
incredibly concise yet crystal clear presentation !
thank you, professor.
Wow, it's a masterpiece! I like the way he introduced the tensor concept. At vid time approx. 36 min, shouldn't it be single integral, not triple?
It's an integral in x,y and z. so should be triple
dm is a function of all x,y,z so three integrals are needed !
i.e. dm = ρdxdydz for uniform body.
great lecture!!..what kept me awake its the hand writing...mine, one would think that am using my feet☺
Thanks, nice lecture, I was looking for information about this topic. I have to go through again though, but it seems very nice organized.
@17:40 Linear momentum
@24:30 Angular momentum
@34:30 Inertia

Thank you sir, very didactic explanation.

Thank you for the great lecture!
Excellent teacher.
Thank you.. GReat lecture. very precise.
Is this lecture for BSc or MSc students ?
thank you very much techer
Great lecture!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
You had me at "rotation about a point".
Can I watch these videos of NPTEL for preparation of GATE ?
someone tell about it please.....
thank you!
sorry, my mistake, they're equivalent, but I don't know which of the two ways is the right one (theorically speaking)
where is the first part?
thanks for posting really appericiated!
Very concise. Thank you
Subtitles are disturbing...
to those who think they wasted their time watching this: it must really suck to be you!
what is the physical meaning of omega x A .. around 7mins
That's a term which takes into effect the rotation of the coordinate system attached to the rotating body. He is saying that when both observers are watching a vector which changes, what they measure as the rate of change is the same once you add in the effect of the rotating reference frame.
This is idea is also where you get things like the Coriolis Force.
It seems if he holds the chalk stationary momentarily after drawing a line, the line perfectly straight. Just like my Apple pencil does on Procreate.

I made it to 3:05 DID I WIN?!
his teaching style did not amazed me because i know that our faculty members of iit's are one of the best faculty members in all over world.
Who the hell is the cameraman, dude you should focus on the board, not on the professor, it is hard to follow him by just listening.
If I am sir
I would be sleeping even there is only 1 day left for exam

oh yes thank you great explaining GUESS WHATT EVERYBODY WIL FALL SLEEP IF WTTHCING THIS
considering the students he is teaching its very simple to understand for them
