Rotational mechanics | Advanced problem | No slipping for just after cutting string

[@ad3398]

This question is awesome , both in concept and calculation. Also greatly explained

[@anmolempire1197]

Awesome, the Explanation at each step make your approach understable to all.. Thank you sir 🙏🏻🌹

[@yatharthgupta6468]

Thanks sir for this problem and explanation Conceptually not very difficult but calculation wise very lengthy

[@madhuagarwal7579]

Thanku sir these questions helps me a lot

[@vedbrahmbhattiit-j4497]

Sir can we write torque abt O ?

[@atikshagarwal5147]

No it is an accelerated point so a non inertial frame of reference hence psuedoforces will act at cm which will produce a non-zero torque ABT the point O

[@atikshagarwal5147]

@@prakharjain5448 bro baat hai ki com is accelerated. Psuedoforces on the body will pass through com. Hence their torque will be zero.

[@DIWAKARKUMAR-ky7jj]

if it rolls just after burning then would it right to take torque about com???? com is also accelerating here

[@krishgarg2806]

even if it is, then the pseudo force would be passing through COM, which would give 0 torque

[@ronitmandal7301]

Why will the normal reaction pass through centre of curvature

[@PhysicswithAkashGoyal]

Normal reaction is perpendicular to the contact surface. For a spherical surface perpendicular must pass through the center of sphere.

[@ponnapu]

sir you have said that it would be better if we not find the acceleration using icor in the icor video but here you are using it .sir is it because the contact point i.e the icor has no acceleration at that instant

[@PhysicswithAkashGoyal]

Yes... It is to be used with care... And sometimes it's use greatly simplifies the problem

Awesome effort ☺️☺️☺️☺️

[@meet2026]

Really helpful video

[@domgesh392]

Sir why we will not consider the centrepital acceleration..

[@PhysicswithAkashGoyal]

For just after release case there is NO velocity and angular velocity. And hence no centrepetal acceleration

[@jkd575]

Good evening sir, Just after releasing angular velocity will be zero, but there will be tangential acceleration

[@Yash-q5g3s]

I dont know why people overcomplicate things so much 😕 It is simple, tan theta would be 8/3 using geometry and balance torque using N=mg

[@PhysicswithAkashGoyal]

N is not equal to mg

[@Yash-q5g3s]

Sorry sir my bad i ment to take torque about icor so only mg will be there

[@Yash-q5g3s]

Great q btw

Is this u sir , your voice seems to be changed

[@PhysicswithAkashGoyal]

I learned to explain better with time...😊

Sir please make a vedio on tough questions of pseudo forces both translation and rotational please please please please please please sir. Pseudo force both rotational and translation

Ok

I don't get this problem sir 😭. Seems to be very difficult, boring & too much stressing.
