WebGears are used for transmitting power from one part of a machine to another. On a bike you push the pedal which in turn will spin the wheels How do gears work? As the first gear turns, it forces the second gear to turn in the opposite direction. By Newtons Third Law, the forces on the teeth of the gears are equal and opposite. WebFor example, a low gear ratio on a bike or car. If the driven gear is smaller than the driver gear it will rotate more quickly - but with a smaller moment. For example, a high gear ratio on a bike or car. Example question. A gear with a radius of 0.1 m is turned by a gear with a radius of 0.05 m. The moment of the smaller gear is 20 Nm.
