The pulleys can turn freely on their pin supports. Their moments of inertia are IA = 0.002 kg-m2, IB = 0.036 kg-m2, and Ic = 0.032 kg-m2. They are initially stationary, and at t = 0, a constant couple M = 2 N-m is applied to pulley A. What is the angular velocity of pulley C and how many revolutions has it turned at t = 2 s?
