FLYWHEEL

Flywheel=> "A flywheel is an inertial energy-storage device. It absorbs mechanical energy and serves as a reservoir, storing energy during the period when the supply of energy is more than the requirement and releases it during the period when the requirement of energy is more than the supply".

Fly wheel of an i.c engine

The main function of a fly wheel is to smoothen out variations in the speed of a shaft caused by torque

fluctuations.

In other words a flywheel stores energy in it, when the supply of energy is more than the requirement and release in it when the requirement of energy is more then the supply.

Applications and examples.

• In I.C Engine=> In an i.c engine, piston supplies torque to the crank shaft only in power stroke(i.e due to the expansion of gases by combustion of fuel), while their is a need of energy or torque to the piston for the completion of remaining strokes of an I.c engine otherwise the engine may stop or variation in output will obtained(if the remaining strokes are not completed).So to overcome this a flywheel is used, which can stores the energy in power stroke and supply back this energy to the piston for completion of remaining strokes.

• Many machines have load patterns that cause the torque time function to vary over he cycle.For e.g=> flywheel is used in the punching press.
