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 figure below shows a block weighing 22 N in contact
with a vertical wall. Two forces are applied to the block, in
addition to gravity, a horizontal force F of magnitude

bottom of the block parallel to the wall. The coefficient of
static friction between the wall and the block is 0.55 and
the coefficient of kinetic friction between them is 0.38. Is
the frictional force acting on the block static or kinetic,
