The small end rollers of the 9.0-lb uniform slender bar are constrained to move in the slots, which lie in a vertical plane. At the instant when \( \theta=32^{\circ} \), the angular velocity of the bar is \( 2.5 \mathrm{rad} / \mathrm{sec} \) 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 \( 4.8-\mathrm{lb} \) 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. The reaction at \( B \) is positive if up and to the right, negative if down and to the left. Answers: i just need to solve the Fb and Fa. Angular acceleration and acceleration for points A and B are given in the picture.
