WebIt was used more than 5000 years ago as a potter wheel. It is an inertial storage device. The energy E stored in a rotating mass is defined by: where J is the mass moment of inertia and w is the angular velocity of the flywheel.For most flywheels, the best design is a cylinder. The mass moment of inertia for a cylinder is defined as: M J=-(RZ ... WebThe resulting gain of kinetic energy in the rotating flywheel assembly (flywheel and axle) is. ... we are assuming that the torsional friction W f is constant over time and angular …
