. The uniform, 6-m slender bar AB weighs x kg and moves in the vertical plane, with its two ends constrained to follow the smooth slot guide. At the position shown where 8 = 45, the bar is released from rest. The mass and size of the end rollers at A and B can be neglected. Slot A 0 6 m B Slot At this instant, determine: a) the angular acceleration of the bar, b) the force on the end roller at A, and c) the force on the end roller at B.
