Introduction
 The turning moment diagram (also known as
crank effort diagram) is the graphical
representation of the turning moment or crankeffort for various positions of the crank.
 It is plotted on Cartesian co-ordinates, in which
the turning moment is taken as the ordinate and
crank angle as abscissa.

The variations of energy above and below the mean resisting torque line are called
fluctuations of energy. The areas BbC, CcD, DdE, etc. represent fluctuations of
energy.

Fluctuation of Energy
 The variations of energy above and below the
mean resisting torque line are called fluctuations
of energy. The areas BbC, CcD, DdE, etc. represent
fluctuations of energy.
 The difference between the maximum and the
minimum energies is known as maximum
fluctuation of energy.

Flywheel
 A flywheel controls the speed variations caused by
the fluctuation of the engine turning moment
during each cycle of operation.
