Rotational Mechanics | Advanced Problem | Three Cylinders & Friction

Three identical solid cylinders are kept as shown on a horizontal surface. Find the initial acceleration of topmost cylinder after the system is released from rest for the two cases:
a) There is friction between the two cylinders and ground but there is no friction between the cylinders such that there is no slipping between ground and the two cylinders.
b) There is no friction with ground but there is friction between the cylinders such that there is no slipping between the cylinders. Advanced problems Playlist

[@ananyagupta1677]

Man I got it all right until the constraint relation😭😭😭. Sir I have to thank you for developing my physics aptitude

[@prakharjain5448]

Same lol I equated for rigid body constraint

[@myselfdreamer50]

Sir make a Playlist for each chapter separately I loved the way u explain although I did the problem on my own but I want to see all ur videos per chapter

[@PhysicswithAkashGoyal]

Chapter wise playlists are already there.

[@adityarajput3908]

Sir please make a particular video about explaining constrained relations properly.

[@Predator-pv7of]

I solved this in david morin sir, still want to watch your explanation cuz I'm sure, I'll learn something new😊

[@vidhitpatel9765]

Sir..in second case for no slipping condition, I equated the acceleration components in x axis rather than y axis...is that correct??

[@atulsoni3895]

Sir kya apke advanced level question ke pdf nahi mil sakte hai kya please sir

[@anvi.gupta3001]

Sir in first case I tried by considering movement of COM of upper sphere as x and lower sphere as y and related them geometrically, followed by conserving energy, and then differentiating the whole equation to get the same answer. Method legit?

[@blazemega1567]

Very nice prob

[@lakshyasharma8519]

Sr what are carrier options in Engineering Physics at IIT or IIS. Please tell

[@korigamik]

And ISS also

[@baly871]

Sir , please suggest best books to improve my concepts as well as problem solving skills.

[@Pushed2InsanityYT]

Hmm, cengage is a good option. It's oriented for JEE and has many problems of Krotov and Irodov inside it already along with other challenging problem. But that book is big as hell so you need a lot of time to solve it.

[@rajendrasharma632]

Sir university physics original or of jee modification?

[@PhysicswithAkashGoyal]

Original

[@lakshyasharma8519]

Don't temper use original. There is a lot difference between classic gr8 physicist and these author who modify books.

[@grandson_f_phixis9480]

Thank you very much sir

[@roxon6929]

Superb SIR ji.

[@keshavjindal445]

Nicely explained

[@yashasvisharma1411]

Sir Resnick halliday walker or krane for theory?

[@PhysicswithAkashGoyal]

Krane

[@yashasvisharma1411]

@@PhysicswithAkashGoyal tnx a lot sir

[@onlyentertainment981]

Won't the torque of (mg of upper cylinder) should also be considered for torque calculation about the center of mass of the lower cylinder?

[@PhysicswithAkashGoyal]

No. I have taken one cylinder as a system for writing equations. In addition to this system of two cylinders is not a rigid system as distance between two points in the two cylinders can vary with time so it will be meaningless to write torque equation for two cylinders.

[@lakshyasharma8519]

It seems u love rotation. Done almost 60 advance illustrations now no iit questions can stop me in rotation.

[@ponnapu]

sir can u post one more rotational mechanics problem today in community sir please

[@yatharthgupta6468]

Nicely done👌

[@harshalasimaiya3621]

Thanku sir

[@aryansudan2239]

done

[@guddudey9786]

Nice

[@guddudey9786]

Nice sir (I know u will give it a Great explanation)
