A system in equilibrium cannot have
A) any forces on it.
B) a non-zero velocity.
C) any torques on it.
D) a non-zero acceleration.

Question

Quizplus · Accepted Answer

A system in equilibrium can have forces and torques acting on it as long as they are balanced, and it can move with a constant velocity (non-zero velocity) as per Newton's first law. However, it cannot have a non-zero acceleration, as this would imply a net force acting on the system, violating the condition of equilibrium.
