For a certain engine having an average speed of 1200 rpm, a flywheel approximated as a solid disc, is required for keeping the fluctuation of speed within 2% about the average speed. The fluctuation of kinetic energy per cycle is found to be 2 kJ. What is the least possible mass of the flywheel if its diameter is not to exceed 1 m ?

Turning Moment Diagrams and Flywheel topics include: Energy fluctuation, flywheel and its energy storage, coefficient of speed and energy fluctuation, turning moment diagram for single and multi cylinder engine and also four stroke cycle combustion engine. A turning moment diagram, also known as a crank effort diagram, is a graphical representation of the relationship between the turning moment and the crank angle at various crank positions. It can be used to design a flywheel for an engine to minimize crank speed variance during each cycle.  A flywheel is a mechanical device that stores... Show more

A turning moment diagram, also known as a crank effort diagram, is a graphical representation of the relationship between the turning moment and the crank angle at various crank positions. It can be used to design a flywheel for an engine to minimize crank speed variance during each cycle. 

A flywheel is a mechanical device that stores energy in the form of rotational momentum. Torque can be applied to a flywheel to cause it to spin, increasing its rotational momentum. This stored momentum can then be used to apply torque to any rotating object, most commonly machinery or motor vehicles. 
The turning moment diagram can also be used to determine the fluctuation of energy for one complete cycle of operation.
