OP9 investigate the law of the lever; recall two everyday applications of levers

equilibrium, the law of the lever, everyday applications of levers

Moment of a force is the product of the force times the distance the force is applied from the fulcrum

The force Mutiplied by the distance

Equilibrium means balanced !

A Lever is a Rigid body free to move about a single point (the fulcrum) which may cause a load to move with an applied force.
