PWE 8-12: A Simple Pulley I
... Our result for the angular acceleration apulley,z depends on the pulling force F, the pulley mass Mpulley, and the pulley radius R. It makes sense that our result is proportional to the ratio F>Mpulley: A greater force F means a stronger pull and a greater angular acceleration, while a greater mass ...

... The above condition is sufficient for a point-like particle to be at its translational equilibrium. However for object with size this is not sufficient. One more condition is needed. What is it? Let’s consider two forces equal magnitude but in opposite direction acting on a rigid object as shown in ...
