A lever is an example of a simple machine. It consists of a bar might be any on which the force is applied at one point and used to overcome resistance at second point by the effect on the third point. The stationary point of lever is known as the FULCRUM.
Principle of lever says:
Opposite forces clockwise and counter clockwise are acting on the lever with equal distance from the fulcrum are said to counteract each other and they maintain a balance(an equilibrium state).
Experiments have shown that when two unequal forces are applied they are said to create equilibrium in a way that the product of magnitude of one force and its effort arm or lever arm(applied force's distance from the fulcrum) is equal to the magnitude of the other force and its effort arm.
Moment of the force: product of force by it's effort arm
Principle of moment: the sum of forces acting clockwise is equal to the sum of forces acting counter clockwise then equilibrium is established.
