The two sliders A and B of weight WA = 8 lb and WB = 6 lb, respectively, move with negligible friction in the slots shown, which lie in the vertical plane. They are connected by a rigid bar of negligible weight and length L = 1.75 ft. Slider A is also subject to the force P = 15 lb. If, for yB = 1.0 ft, the system is initially at rest, determine the acceleration of each slider and the force in the bar immediately after release. Hint: The force that the bar exerts on each slider has the same direction as the bar itself.
