Question

Write the formula for moment of inertia of flywheel

Answer 1

A flywheel is a mechanical device specifically designed to efficiently store rotational energy. Flywheels resist changes in rotational speed by their moment of inertia. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. ... Smoothing the power output of an energy source.

Answer 2

mgh=½mv²+½Iw²+nE

This gives

I=2(mgh-½mv²-nE)/w²
