Three simple machines are lever, wheel and axle, and pulley. The lever has two parts the fulcrum which is in the middle and the effort and load which are on the sides. The lever increse forces and can be adjusted by moving the fulcrum. The wheel and axle has an axle and a wheel then in the middle of the axle theres the fulcrum. The pulley is used to change the direction of a force and make work eaiser. It also has a effort load and a fulcrum.
