This is a small wheel with a grooved rim through which a rope of chains run. It changes the direction of a pulling force and combinations of these simple machines increase the force applied for lifting an object.

Gear

This is a toothed wheel that engages another toothed mechanism in order to change the speed or direction of transmitted motion.

Distance

This is the gap or measurement between two location.

Lever

This is a class of rotating machines or devices in which effort applied to one part produces a useful movement at another part. They are used for moving of lifting loads.

Force

This is an influence that produces a change in an object.

Lever

This simple machine is a rigid bar that pivots on a fulcrum to move or lift a load.

Inclined Plane

This simple machine is a slope or ramp that is used to lift a load. It trades distance for force

Wedge

This is a combination of two inclined planes that is if itself moved with force to cut apart or separate an object.

Wheel and Axel

This is a class of rotating machines or devices in which effort applied to one part produces a useful movement at another part. They are used for moving or lifting loads.
