What Is Static Equilibrium?

In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its individual parts is zero.

What is meant by static equilibrium?

Static equilibrium refers to any system where the sum of the forces, and torque, on every particle of the system happens to be zero. Simply, it is the equilibrium of a system whose parts are at rest.

What is an example of static equilibrium?

1: In a torque balance, a horizontal beam is supported at a fulcrum (indicated by S) and masses are attached to both sides of the fulcrum. The system is in static equilibrium when the beam does not rotate. It is balanced when the beam remains level.
