Can a gear drive change the force of a small force? How does it get bigger?
But work does not change because the distance you do work increases
The distance between the hand and the axle of your shaking handle is R (R>r)Then you use the power of F, and the output is FR/r
Lever like?For example, you turn a gear with a radius of r,
It can be said is. The gear transmission torque or force amplifier. Gear transmission is power, the two gear to get power (or size equal to the torque speed is equal to x), is inversely proportional to torque and speed. The small gear radius is small and fast speed, small torque and large gear radius; the rotational speed and torque. The route: the big gear pinion, it can force amplification.
