Homework Statement
Consider an isolated system consisting of a large number N of very weakly interacting localized particles of spin 1/2. Each particle has a magnetic moment \mu which can point either parallel or antiparallel to an applied field H. The energy E of the system is then E =...
Thank you so much for that hint, it was exactly what I needed to get on track. In order to stay on the circular path, some force has to pull the cylinder towards the center of the big cylinder with force mv^2/r, so the only force that can do that here is gravity (so friction isn't really...
1. The problem:
A Uniform right-cylinder of radius a is balanced on top of a perfectly rough (so that only pure rotation occurs) fixed cylinder of radius b (b>a), the axes of the two cylinders being parallel. If the balance is slightly disturbed, show that the rolling cylinder leaves the fixed...
