Question

Coefficient of fluctuation of energy is ratio of _______

(a) Mean fluctuation energy to work done per cycle

(b) Maximum fluctuation energy to work done per cycle

(c) Minimum fluctuation energy to work done per cycle

(d) Mean fluctuation energy to power generated per cycle

I got this question at a job interview.

I'm obligated to ask this question of Coefficient of Fluctuation of Energy topic in division Turning Moment Diagrams and Flywheel of Machine Dynamics

Answer 1

Correct choice is (b) Maximum fluctuation energy to work done per cycle

For explanation I would say: The ratio of the maximum fluctuation of energy to the work done per cycle is known as the coefficient of fluctuation of energy. Mathematically, coefficient of fluctuation of energy (CE) = Maximum fluctuation of energy/Work done per cycle.
