The small end rollers of the 6.2-lb uniform slender bar are constrained to move in the slots, which lie in a vertical plane. At the instant when e = 30°, the angular velocity of the bar is 2.6 rad/sec counterclockwise. Determine the angular acceleration of the bar, the reactions at A and B, and the accelerations of points A and B under the action of the 5.1-lb force P. Neglect the friction and mass of the small rollers. The angular acceleration is positive if counterclockwise, negative if clockwise. The acceleration of A is positive if downward, negative if upward. The acceleration of B is positive if down the slot, negative if up the slot. The reaction at A Is positive If to the right, negative If to the left.
