n case of a single cylinder double acting steam engine, 180 kW power is being developed at a mean speed of 120 r.p.m. The coefficient of fluctuation of energy is 0.12. The fluctuation of speed is ± 2% of mean speed. The flywheel rim has mean diameter of 2 metre. The hub and spokes of the flywheel provide 8% of the rotational inertia of the flywheel. If the density of the flywheel material is 7200 kg/m3, determine the mass and cross-sectional area of the flywheel rim.

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
