What is meant by "static equilibrium"?

Static equilibrium refers to a state in which an object is at rest and experiences no net force acting upon it. This means that all the forces acting on the object are balanced, resulting in no movement. For an object to be in static equilibrium, not only must it be stationary, but the forces that act on it, such as gravitational force and normal force, must cancel each other out.

This concept is vital in mechanical comprehension, as it allows us to analyze situations where structures or objects maintain stability without any motion. Recognizing that static equilibrium is characterized by a state of rest and balanced forces helps in understanding various physical principles involved in engineering and physics.
