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.
Examples: 1  Human arm. 2  Tongs (double lever) (where hinged at one end, the style with a central pivot is first-class). 3  Catapult and fishing rod (catapults that act as a see-saw, catapulting their load when something of great mass lands on the board on the opposite side of the fulcrum are first-class levers.
