homogeneous sphere weighing 50 lb rests against two smooth planes that form a V-shaped trough as shown in. Determine the forces exerted on the sphere by the planes at contact points A and B.

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.

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