For a system in mechanical equilibrium
A)the resultant force must be zero.
B)the resultant torques must be zero.
C)the resultant forces and torques must both be zero.
D)the resultant forces and torques must be equal.

Question

Quizplus · Accepted Answer

For a system in mechanical equilibrium, both the resultant forces and torques must be zero. This means that the sum of all forces and torques acting on the system must be balanced and there is no net external force or torque causing a change in the motion or rotation of the system.
