Question:
The change in kinetic energy ΔE of an engine is 300 J, and minimum and maximum shaft speeds are wmin = 220 rad/s and wmax = 280 rad/s, respectively. Assume that the torque-time function is purely harmonic. To achieve a coefficient of fluctuation of 0.05, the moment of inertia (in kg.m2) of the flywheel to be mounted on the engine shaft is
