Gears
Gears are wheels with toothed edges. The toothed edges of one gear can fit into the edges of another.
Force multipliers
- Gears can be described as force multipliers.
- Force multipliers are simple machines.
Using gears to change force
- A force can be passed through the gears.
- If a force is passed through a large gear to a small gear (from A to B), the force is increased.
- If a force is passed through a small gear to a large gear (from B to A), the force is decreased.
