A body remains at rest under the action of several forces. This state is called:
ADynamic equilibrium
BInertial equilibrium
CStatic equilibrium
DFree equilibrium
Answer & Solution
Correct answer: C. Static equilibrium
1. Equilibrium happens when net force and net moment are zero.
2. If the body is at rest, the state is called static (or stable) equilibrium.
3. If the body moves with constant velocity instead, it is called dynamic equilibrium.
4. The given body is at rest, so the answer is static equilibrium.
