Complete Question:
If an object in translational equilibrium is also in rotational equilibrium about a given rotational axis the object will be in rotational equilibrium about any other axis. True or false
Answer:
True
Explanation:
An object is in translational equilibrium when the sum of all the external forces acting on it equals zero.
Such an object is also experiencing zero overall acceleration. Therefore, it is either not moving or moving at a constant velocity
An object is in rotational equilibrium when the sum of all the external torques acting on it equals zero.
Such an object either will not be moving or moving at a constant angular velocity. This means the object is experiencing zero angular acceleration
If an object in translational equilibrium is also in rotational equilibrium about a given rotational axis the object will be in rotational equilibrium about any other axis
