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 t = 3 s if a constant torque M = 2 lb • ft is applied to the shaft. The shaft is originally spinning at ω1 = 8 rad/s when the torque is applied.
