Question

define mechanical equilibrium of a rigid body ​

Answer 1

Answer:

Explanation:

A rigid body is said to be in mechanical equilibrium, if both its linear momentum and angular momentum are not changing with time. In other words, the body is in mechanical equilibrium when it has neither linear acceleration nor angular acceleration.

Answer 2

Answer:

ANSWER

Explanation

ExplanationEquilibrium is a defined as any point where the total amount of external force or torque is zero. This point may be anywhere near the center of mass. External force in translational motion of the rigid body changes the linear momentum of that body. While the external torque in rotational motion can change the angular momentum of the rigid body.
