Q. |
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 |
Answer» B. helps the engine in keeping the speed uniform | |
Explanation: 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. |
