21-27. The circular disk has a weight of 15 lb and is mounted on the shaft AB at an angle of 45° with the horizontal. Determine the angular velocity of the shaft when 1 = 2s if a torque M = (4e 0.lt) Ib - ft, where t is in seconds, is applied to the shaft. The shaft is originally spinning at w, = 8 rad/s when the torque is applied. 0.8 ft 45° w = 8 rad/s M.
