The sum of the moments (torques) about any arbitrary point must be zero (
The vector sum of all external forces acting on the body must be zero ( ). In a 2D plane, this resolves into two scalar equations:
). This ensures the object does not rotate or change its angular velocity. 2. Types of Equilibrium

An object is in equilibrium if it remains at rest or moves with a constant velocity. This state is governed by two primary laws:
