In a turning moment diagram, the variations of energy above and below the mean resisting torque line is called
(a) fluctuation of energy
(b) maximum fluctuation of energy
(c) coefficient of fluctuation of energy
(d) none of the mentioned
I have been asked this question by my college director while I was bunking the class.
My doubt is from Energy Stored in a Flywheel topic in section Turning Moment Diagrams and Flywheel of Machine Dynamics
