Kindly see post#57 and 58. The conclusion that I'm gathering from those 2 posts is this: The net angular accleration about point C will...

I would like your response on this question.

Good. That's unlikely to work. Energy conservation equations are time independent . No, you can't do that. The motion of a rigid body...

I've figured out where the sign convention went wrong, and have arrived at the correct answer. @haruspex, @kuruman : Appreciate your...

https://en.wikipedia.org/wiki/Moment_of_inertia disagrees. "The moment of inertia, otherwise known as the mass moment of inertia...

As I wrote in post #28, the moment of inertia of a body is only of interest in the context of rotation about some axis. To put that...

I would argue strongly against thinking of this "effective MoI" as really being an MoI. MoIs arise usually in three contexts: Angular...

Yes, you do seem to have a sign error in post #59, but where exactly it is depends which sense you are taking as positive for each...

yes, and it is already negative, before we proceed on to do factorization. Kindly see last line in post#59. So, eventually...

After factorizing, in the denominator I'm getting: ##(r - R)##, where ##(R - r)## should come. I've double checked my...

Factorise the denominator.

I don't understand how does that reduce to this equation. Even if we neglect the small r term in the numerator, we can't neglect the...

Here's the calculation taking the angular momentum about point C. ## L_{aboutC} = -mw_{C}(R-r)^2 + \frac{2}{5}mr^2w_{cm} ## and using...

Yes, i agree that that is what you were saying. I'm not sure why you thought I was disagreeing with you on this point. In the statement...
