A 6.00 m uniform beam of mass 17.0 kg is hinged to a vertical wall. The beam is kept in a stationary horizontal position by an 8.00 m cable. One end of the cable is attached to the other end of the beam while the other end of the cable connects to the vertical wall 4.00 m above the hinge. When a 10.0 kg crate is placed on the beam 5.00 m from the vertical wall the system is in equilibrium.

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.
