Like.
Factorise the denominator. -
NNTesla replied to the thread Rolling without slipping on a curved surface.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...

NNTesla replied to the thread Rolling without slipping on a curved surface.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...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.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...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.Not really, because I already do understand that. In my calculation that I have attached as pdf in post#24, I have already written that...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.Agreed. I don't agree. There is a definite non-zero moment of Inertia about C, and finding it could possibly lead to increase in...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.I'm not sure how that would help in finding out the moment of Inertia of the ball about the axis passing through point C, in the present...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.my bad. I mistakenly wrote "wouldn't", when it should have been "would". The correct statement is: If the mass distribution doesn't...

-
NNTesla replied to the thread Rolling without slipping on a curved surface.So, if the mass distribution doesn't change just because the ball is rotating, this means the moment of inertia should not change just...

NNTesla replied to the thread Rolling without slipping on a curved surface.@haruspex, @kuruman Your opinion on this.
-
NNTesla replied to the thread Rolling without slipping on a curved surface.Will the distribution of mass change just because the ball is rotating ?
-
NNTesla replied to the thread Rolling without slipping on a curved surface.This I do understand. But let's say, we have a solid sphere which is just lying at the bottom most point of the concave surface. Not...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.Since we are taking torque about axis passing point C, and moment of Inertia is only the distribution of mass about axis passing through...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.And I'm applying the parallel axis theorem. But apparently, in it's application something other than what I've done in the pdf file, is...
-
NNTesla replied to the thread Rolling without slipping on a curved surface.Is the moment of Inertia dependent upon whether a body is actually rotating about some axis or not. Can a body not have moment of...
