Translational equilibrium requires the total external force to be:
AExactly zero
BAt a maximum
CKept constant
DKept positive
Answer & Solution
Correct answer: A. Exactly zero
1. A rigid body in equilibrium must not accelerate as a whole.
2. That needs the forces on it to cancel.
3. So the total external force is zero.
