The L shape slender bar of mass m = 5 kg and b = 2m can move easily in the vertical plane with no friction on the vertical and C b/2 horizontal surfaces as shown. If the bar is released from rest in the position where 0 is 15o and the spring with k=100N/m is unstretched and also under the b action of a couple M of constant magnitude of 200 N-m applied to AB, determine the angular velocity of the bar as e becomes 45o, M k A www assume g= 10 m/s2.
