If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be
(a) four times the first one
(b) same as the first one
(c) one fourth of the first one
(d) one and a half times the first one
This question was posed to me during an online interview.
This key question is from Flywheel in chapter Turning Moment Diagrams and Flywheel of Machine Dynamics
