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 uniform 50-lb beam is supported by the rope that is attached to the end of the
beam, wraps over the rough peg, and is then connected to the 100-lb block. If the
coefficient of static friction between the beam and the block, and between the rope
and the peg, is H, = 0.4, determine the maximum distance that the block can be
placed from A and still remain in equilibrium. Assume the block will not tip.
