The sliders A and B are connected by a light rigid bar of length I = 19 in. and move with negligible friction in the slots, both of which lie in a horizontal plane. For the position where xA = 13 in., the velocity of A is va = 4.0 ft/sec to the right. Determine the acceleration of each slider and the force in the bar at this instant. The acceleration of A is positive if to the right. The acceleration of B is positive if up (as viewed in the diagram). The force in the rod is positive if in tension. Remember that the motion takes place in a horizontal plane, so the force of gravity is not a factor. 9.3 lb B 19 in. 5.9 Ib P = 16 lb

A fixed-end beam AB supports a uniform load of Intensity q = 29.7 Ib/ft acting over part of the span. Assume that EI = 300 kip-ft. (Solve by the method of superposition. Assume the +x-direction is to the right, the +y-direction is upward, and the positive direction for moments is counterclockwise. Unless otherwise stated, use the statics sign convention.) 9f (a) Calculate the reactions at A and B. (Enter your forces in kips and your moments in kip-ft.)

Beam AB has a negligible mass and thickness, and it supports the 200 kg uniform block. It is pinned at A and rests on the top of a post, having a mass of 20 kg and negligible thickness. Determine the two coefficients of static friction at B and C so that when the magnitude of the applied force is increased to P = 300 N, the post slips at both B and C simultaneously.
