An energy of `484 J` is spent in increasing the speed of a flywheel from 60 rpm to 360 rpm. Calculate moment of inertia of flywheel.

To increase the speed of a flywheel from 60 rpm to 360 rpm, energy of 490 J is spent. Calculate the moment of inertia of wheel.

The angualr speed of a flywheel making 360 rpm is

The angular speed of a flywheel rotating at 90 r.p.m . Is

If 600J of energy is spent in increasing the speed of a wheel from 60 rpm to 240rpm the M.I.of the wheel is.[(pi^(2)=,10) (A) "2kgm^(2) (B) 3kgm^(2) (C) 4kgm^(2) (D) 5kgm^(2)

To speed up a flywheel from 60rpm to 120 rpm, energy equal to 9000 J is requires. Calculate the moment of inertia of flywheel. Also calculate change in angular momentum of flywheel.

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)

When the speed of a flywheel is increased from 240 r.p.m. to 360 r.p.m., the energy spent is 1936 J. What is te moment of inertia of the flywheel?

A unifrom horizontal disc is freely rotating about a vertical axis through its centre at the rate of 240 rpm. A blob of wax of mass 2 g falls on it and sticks to it at 25 cm from the axis. If the frequency of rotation of the disc is reduced by 60 rpm. calculate the moment of inertia of the disc. lt

The flywheel of a gasoline engine is required to give up 300 J of kinetic energy while its angular velocity decreases from 600 rev min^(-1) to 540 rev. min^(-1) . What is the moment of inertia of the flywheel ?

A flywheel rotating about an axis through its centre and peropendicular to its plane loses 10pi^(2) J of energy on slowing donw from 60 rpm to 30 rpm. Find its moment of inertia about the given axis and the change in its angular momentum.
