Q842
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
AnswerC.
Decreases the moment of inertia
D.
Gives strength to the engine
Answer: Option B
Solution
Answer: 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.
