Answers
Answer:
Equilibrium
a state of rest or balance due to the equal action of opposing forces. equal balance between any powers, influences, etc.; equality of effect. mental or emotional balance; equanimity: The pressures of the situation caused her to lose her equilibrium.
Explanation:
Translational equilibrium
An object is in translational equilibrium when the sum of all the external forces acting on the object equals zero. This also means an object is in translational equilibrium when it is experiencing zero overall acceleration. Therefore, it is either not moving or moving at a constant velocity.
Rotational equilibrium
An object is in rotational equilibrium if the velocity of its rotation is constant. An object that is not rotating or an object that is rotating in one direction a constant rate would be considered in rotational equilibrium. To be in rotational equilibrium, the net torque acting on the object must be zero.
Static equilibrium
An object is in static equilibrium if and only if: The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero
