Question
Q8: 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.
Ans.: F, = 234 N, a = 5.87 rad/s² CW
