A gear is a wheel with teeth that meshes with the teeth of another gear to transmit power on a continuous basis. Combining gears of different diameters affects rotation speed and force.
All out cars have gears they are also very useful into transmissions for industrial machines.

The production of a gear starts from a large round bar of high- grade steel which contains a certain amount of carbon to make it even stronger.
The process of making a gear is amazing.
