When 'W' joule of work is done on a flywheel, its frequency of rotation increases from `n_(1)`. Hz to `n_(2)`. Hz The M.I. of the flywheel about its axis of rotation is given by

When 200 J of work is done on a fly wheel its frequency of rotation increase from 4Hz to 9 Hz . The M.I. of the wheel about the axis of rotations is nearly

When 200J of work is done on a fly wheel its frequency of rotation increases from 4Hz to 9Hz . The M.I. of the wheel about the axis of rotation is

When a 12000 joule of work is done on a flywheel, its frequency of rotation increases from 10 Hz to 20 Hz. The moment of inertia of flywheel about its axis of rotation is (pi^(2) = 10)

A flywheel of mass 100 kg and radius 1 m is rotating at the rate of 420 rev/min. Find the constant retarding torque to stop the wheel in 14 revolutions, the mass is concentrated at the rim. M.I. of the flywheel about its axis of rotation I = mr^(2) .

The angular momentum of a body is 31.4js and its rate of rotation is 10 hz. calculate moment of inertia of the body about given axis of rotation.

If the speed of rotation of earth about its axis is increased,

A flywheel rotating about a fixed axis has a kinetic energy of 225 J when its angular speed is 30 rad/s. What is the moment of inertia of the flywheel about its axis of rotation?
