Principle of the Lever. It has been found by experiment that two equal forces acting in opposite directions, i.e., clockwise and counterclockwise, and applied to a uniform lever at equal distances from the fulcrum counteract each other and establish a state of equilibriumequilibrium, state of balance.
Terms associated with levers: 1  Fulcrum: the pivot point of a lever. 2  Effort: the force applied to a lever. 3  Resistive force, load or resistance: force that resists the motion of the lever. 4  Moment arm: the perpendicular distance from the line of action of the force of the fulcrum. 5  Mechanical advantage: ratio of output force : input force.
