Question

Which is the false statement about a flywheel?
(1) Flywheel smoothens the cyclic fluctuation of speed
when delivering constant output power
(2) It has no influence on the mean speed of the prime
mover
(3) It takes care of output fluctuation and controls input
accordingly
(4) It has no influence over the varying load demand on
prime mover

Answer 1

4 statement is wrong for flywheel

Answer 2

(3) It takes care of output fluctuation and controls input.

FLYWHEEL: It is a machine which uses the concept of conservation of angular momentum and store rotational kinetic energy.

Fuctionalities of flywheel:

• Flywheel smoothens the cyclic fluctuation of speed by providing smooth delivery of power to the machine.
• The function of taking care of output fluctuation is performed by the generator.
• The generator controls the mean speed of the load when there is any fluctuation in the load.

As Flywheel stores rotational kinetic energy, it is used as a congener of the electrical inductor.
