NNTesla replied to the thread Rolling without slipping on a curved surface.I don't understand why it doesn't make sense. In undergraduate level physics books, that's how angular velocity and angular acceleration...

NNTesla replied to the thread Rolling without slipping on a curved surface.I understand your arguments and the calculation. However, In view of that wikipedia statement, and your arguments and calculation, I'm...

Like.
I have a problem with the idea of adding angular accelerations this way to calculate the moment of inertia because they are about... -
NNTesla replied to the thread Rolling without slipping on a curved surface.I must admit, I can understand each word individually, but I couldn't understand what you wanted to say there, at all. Kindly explain...

NNTesla replied to the thread Rolling without slipping on a curved surface.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...

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

NNTesla replied to the thread Rolling without slipping on a curved surface.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...

NNTesla replied to the thread Rolling without slipping on a curved surface.yes, and it is already negative, before we proceed on to do factorization. Kindly see last line in post#59. So, eventually...

NNTesla replied to the thread Rolling without slipping on a curved surface.After factorizing, in the denominator I'm getting: ##(r - R)##, where ##(R - r)## should come. I've double checked my...
