Problem 4 - Torque An Atwood machine consists of two masses my = 7.9 kg and my = 6.3 kg, connected by a cord that passes over a pulley free to rotate about a fixed axis. The pulley is a solid cylinder of a radius Ro = 0.35 m and a mass M =0.40 kg. The moment of inertia of the pulley with respect to the axis around which the pulley is rotating in this problem is I = MR;/2. . Draw the free body diagram for each of the two masses and for the pulley. (5 points) . Calculate the acceleration (magnitude and direction) of the weights. (10 points) 0
