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

Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.

Question

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 XẠ = 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.
