Turning moment diagram and flywheel.

NOTE:

[1] Coefficient of fluctuation of energy.

$C_E = \frac{maximum \ fluctuation \ of \ energy}{Work \ done \ per \ cycle} = \frac{\triangle E}{W.D/cycle}$

Where $\triangle E$ = maximum energy – minimum energy.

i.e.

$\triangle E = E_1 – E_2$

$\rightarrow$ $W.D/Cycle = T_{mean} …
