GEARS

GEARS
Gears have been around for hundreds of years. The first mention of gears came from Aristotle in the year 330 BC, who used the devices for various construction jobs. He observed that the direction of rotation is reversed when one gear wheel drives another gear wheel. At that time, gears were also used in making water-raising devices and to make catapults.  You can have any number of gears connected together and they can be in different shapes and sizes.
