Rotational Equilibrium And Rotational Dynamics

In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.

Equilibrium of Forces

The tension created on one body during push or pull is known as force.

Question

A uniform bar 9 ft long and weighing 5 Ib. is supported by a fulcrum 3ft from the left end. If a
12-lb load is hung from the left end
What downward pull at the right end is necessary to hold the bar in equilibrium? Include
the illustration.
What force does the fulcrum push up against the bar?
