Hello, I am first year mechanical engineering student and I am struggling with the concept of moment, rotation and angular velocities, accelerations of rigid bodies. Can someone recommend an article with problems or an excerpt from a book or something similar to help me. It would be great if...

No. Yeah thanks a lot for the help.

Ohh now I see what you mean. Should be static?

The question did not say. But when you compute the velocity using the force method or the energy method (while using the second one assume no friction force) and the answer is the same. I do not quite understand the solution probably that's the problem itself.

An object (for example cylinder) is rolling down an incline, with no slip. We know there is some friction and we have to find the velocity of the objects. There are 2 ways of doing so with calculating resultant force and using Newton's laws and the energy method. Why is it that when we are using...
