Question

State the two conditions that need to be satisfied for a rigid body to be in mechanical equilibrium​

Answer 1

Answer:

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.

Answer 2

Explanation:

1. The sum of all external forces acting on the body is zero

2. The sum of all the torques from external forces is zero.
