The 25-kg circular disk is attached to the yoke by means of a smooth axle A. Screw C is used to lock the disk to the yoke. If the yoke is subjected to a torque of M = (5t²) N · m, where t is in seconds, and the disk is locked, determine the angular velocity of the yoke when t = 3 s, starting from rest. Neglect the mass of the yoke.
