coefficient of fluctuation

The change in kinetic energy ΔE of an engine is 300 J, and minimum and maximum shaft speeds are ω_min = 220 rad/s and ω_max = 280 rad/s, respectively. Assume that the torque-time f...

The change in kinetic energy $\Delta E$ of an engine is $300$ J, and minimum and maximum shaft speeds are $\omega_{min} = 220$ rad/s and $\omega_{max} = 280$ rad/s, respectively. A...

If $${C_f}$$ is the coefficient of speed fluctuation of a flywheel then the ratio of $${\omega _{\max }}/{\omega _{\min }}$$ will be
