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

The man is holding up the 35-kg ladder ABC by pushing perpendicular to the
ladder. The total length of the ladder is AC= 6m. If the maximum force that the man
can exert is 400N at B which is 2m from A, determine the smallest angle, theta, at which
the man can support the ladder.
