A cam is a shaped frame turning about an axis, like a rotating wheel. Cams can control the timing and degree of movement.
The gear is a simple machine that can be used to efficiently transfer force and motion.
The inclined plane is a slanted surface used to raise objects.
Pawl and ratchet is a simple machine that is used in connection with gear mechanisms to allow linear or rotary motion in only one direction.
A pulley is a simple machine that can be used to lift objects and transmit motion. Pulleys can be either movable or fixed and multiple pulley wheels on one axle can be used ad block and tackle.
The screw is a simple machine and a modification of an inclined plane.
Structures is a simple machine in which individual parts are arranged to form a whole. All structures are under the influence of external and internal forces.
The wedge is a simple machine that is a modification of an inclined plane, however a wedge can move.
Wheel and Axle is a simple machine, often a big wheel and a small axle, which is secured to one another. A wheel and axle always rotate at the same speed.
