A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. Energy is transferred to a flywheel by applying torque to it, thereby increa...

A device used for storing mechanical energy and for smoothing the power output of an engine, comprising a heavy shaft-mounted wheel. Since energy is stored as kinetic energy of rotation, it is advantageous for the wheel to have as large as possible a moment of inertia, and thus for its mass to be co...

Heavy wheel in an engine that helps keep it running and smooths its motion. The crankshaft in a petrol engine has a flywheel at one end, which keeps the crankshaft turning in between the intermittent power strokes of the pistons. It also comes into contact with the clutch, serving as the connection between the engine and the car's transmission ...
