6/25 The 25-kg bar BD is attached to the two light links AB and CD and moves in the vertical plane. The lower link is subjected to a clockwise torque M=200 N m applied through its shaft at A. If each link has an angular velocity w = 5 rad/s as it passes the horizontal position, calculate the force which the upper link exerts on the bar at D at this instant. Also find the angular acceleration of the links at this position. T 300 mm 500 mm D C B 600 mm M Problem 6/25
