Which among the following, generally have high value of coefficient of fluctuation speed for flywheel?
DSSSB - 2023,
Answer: A
Automobile engines of normal speed are given as having a high coefficient of fluctuation of speed in the key. The coefficient of fluctuation of speed for a flywheel is the ratio of the change in speed to the mean speed. Machines that need smooth running, such as machine tools, weaving machines and belt driven generators, are given smaller values, because a smaller value means a more uniform speed.
