The 26-kg rod AB is pin-connected at A and subjected to a couple moment of M=15 N. m. The rod is released from rest when the spring is unstretched at 0 = 30. As the rod rotates, the spring always remains horizontal, because of the roller support at C. Part A k = 40 N/m B 0.75 m M 15 N-m Determine the rod's angular velocity, measured clockwise, at the instant 0 = 60. Express your answer in radians per second to three significant figures. Enter positive value if the angular velocity is clockwise and negative value if the angular velocity is counterclockwise. vec ? 3 11 Submit Request Answer rad/s
