The 14-kg bar AB is pivoted at A and is subjected to a moment M = 18 N.m. If the bar is released from rest when the spring is at its natural length at an angle 0 = 30°, determine the angular velocity of the bar at the instant 0 = 60°. Assume that the spring, thanks to the presence of the roller at C, always remains horizontal.
