System of Forces

A force is an external influence or agent that changes the state of a system. According to Newton's second law, the force applied to a body is proportional to the change in momentum of a body. Hence, whenever a force is applied to a body, its momentum changes. If the body is at rest, under the action of force, its state of rest changes to motion. In other words, the magnitude of the momentum of the body changes from zero to a measurable value. Similarly, if the body possesses some initial velocity, it has some associated momentum, the effect of force can cause the body to halt or come to rest, that is, the momentum reduces to zero.

Pictured below is a smooth bar (no friction) held in position by a pin and contact with the wall on the left end and subjected to a vertical load P at the right end. Find the distance d that the force needs to be along the bar for equilibrium given the pin is a distance a away from the wall and the bar makes an angle 0 with the horizontal. The weight of the bar is negligible. (Hint: Use the three equations of equilibrium and solve for d. The values for a, 0, and Pare constants.)
