Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Gear system or box is a transmission system of power which is used in all type of vehicles. Gear is a speed and torque changing device used between the engine and the driving wheels. It is a simple machine used to generate more speed or power or send the power of machine in another direction.
