If the moment of forces in a system are balanced and their magnitudes are equal, the forces must be acting in opposite directions, and the system is said to be in a state of equilibrium. This means that there is no net force or torque acting on the system, which results in no acceleration or change in its motion. The forces must also be acting along the same line of action, or they must be equidistant from the pivot point or fulcrum to maintain this equilibrium.
