At the time when we invented wheel, which was a very helpful product to help a person to transport thing from one place to another. After the success of invention of wheel, people invented one more thing called gears. Gears which is like a wheel with teethes at the edge which rotates with another gear having similar kind of teethes to reduce the force and increase the energy.
In other words, gears are rough wheels with cutting edges that transmit motion and energy when meshed with another gear or a compatible device. Positive transmission is transferred and accomplished whenever the teeth of the gear work in conjunction with another.
Gears started by someone in fourth century, but now been used by almost everyone.
In our life we all are using gears to reduce our effort and investment of time and increase the energy like - Car, clock, Juicer Mixer Grinder (JMG), generators, elevators, lifts, VCR, power meters, wrist watches etc
