The uniform slender bar of mass m = 3.6 kg and length L = 1.18 m with small end rollers is released from rest in the position shown (0 = 29") with the lower roller in contact with the horizontal plane. Determine the normal force N under the lower roller and the angular acceleration a of the bar immediately after release. The angular acceleration is positive if counterclockwise, negative if clockwise. Answers: N
