2. Flywheel is an important part of a steam engine because it : 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
Option 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.
