Problem: Two forces are acting on an object. Which of the following statements is correct?a) The object is in equilibrium if the net torque on the object is zero.b) The object is in equilibrium if the forces are equal in magnitude and opposite in direction.c) The object is in equilibrium if the net force and the net torque on the object are both zero.d) The object cannot be in equilibrium because more than one force acts on it.e) The object is in equilibrium if the forces act at the same point on the object.

FREE Expert Solution

Equilibrium can either be rotational or translational. 

Translational equilibrium occurs if the net force acting on the object is zero.
