1. The problem statement, all variables and given/known data Consider the pulley to be ideal. If the system disturbed from its equilibrium position by pulling the right hand mass down a slight amount and then released, determine the frequency and period of the oscillation. Radius of pulley is r=2m and I bar of the pulley is 10kg/m2. here is the picture: http://i26.tinypic.com/2hzu2yg.jpg I got f=0.982hz and T=1.01s Is that correct?
