1. The problem statement, all variables and given/known data

wouldn't the initial angular speed of 50rad/s cause some rotation about the axis at B (so shouldn't the FBD include a torque about B?)

And in this question, I don't know what Mz is. Is it due to the angular speed of 60000rpm?
2. Relevant equations
3. The attempt at a solution
