9 in. 4 M A constant moment M in the clockwise direction is applied to a 20-lb thin disk in contact with an inclined surface. The kinetic friction coefficient is ur at the point of contact D. Determine the magnitude of the angular acceleration of the disk by neglecting the weight of the link AB, if M = 7.5 lb.ft and fx=0.4. Present your answer in rad/sec using 3 significant figures. 1 in = 1/12 ft. B D 30°
