The particle of mass m = 0.6 kg is attached to the end of the light rigid bar of length l = 0.7 m. The system is released from rest while in the horizontal position shown, at which the torsional spring of stiffness kt = 15 N.m/rad is undeflected. A variable moment M = 120, where M is the moment in N.m and is the angle of the bar with the horizontal in radians, is acting on the bar, as shown. Determine (a) the angular velocity of the bar as it passes the orientation 0 = 40°, and (b) the angle where the bar stops momentarily. (w = 3.61 rad/s, 0 = 94.8°) M Ꮎ l m
