(b) It is the ratio of the maximum and minimum energies

(c) It is the ratio of the mean resisting torque to the work done per cycle

(d) It is the difference between the maximum and minimum energies

I have been asked this question in an online quiz.

My question is based upon Flywheel in division Internal Combustion Engines of Automobile Engineering

Answer 1

Correct option is (d) It is the difference between the maximum and minimum energies

Best explanation: The maximum fluctuation of energy is the difference between the maximum and minimum energies. The fluctuation of energy can be found out by the turning moment diagram for one complete cycle of operation.
