The rod is attached with ballandsocket joints to smooth coll

The rod is attached with ball-and-socket joints to smooth collars A and B at its end points. The angular velocity of the rod is directed perpendicular to the axis of the rod. The collar at A is moving upward with an acceleration of aA={?2k}ft/s^2, at the instant its speed is vA = 4.6 ft/s

Solution

From the given data

Y component of the acceleration = 38ft/sec

Answer= 38ft/sec

Answer= 38ft/sec
