A) accelerates the speed of the engine
B) helps the engine in keeping the speed uniform
C) decreases the moment of inertia
D) gives strength to the engine
Correct Answer: B
Solution :
A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant moment of inertia and thus resist changes in rotational speed, enabling the engine to run at a constant, uniform motion. In the Industrial Revolution, James Watt contributed to the development of the flywheel in the steam engine.
