Conditions of equilibrium

There are two conditions of equilibrium.

First condition of equilibrium:

Vector sum of all the forces acting on the object is zero.

Second condition of equilibrium:

The algebaric sum of all the moment of forces acting on an object iz zero. i.e.

Sum of anticlock wise moment of forces = Sum of clock wise moment of forces
