The acausal bond graph of system \textbf{Clutch} is displayed in
Figure \Ref{Clutch_abg} and its label file is listed in Section
\Ref{sec:Clutch_lbl}. The subsystems are listed in Section
\Ref{sec:Clutch_sub}. The details of the DC motor and the load are
hidden behind a word bond graph so as to focus on the clutch
mechanism as modelled by the \textbf{CSW} component.
It is natural to model the clutch shaft by a
compliance to absorb the shock of engaging the clutch; therefore the
drive model contains a \textbf{CSW} component.
Figure \ref{fig:Clutch_odeso-noargs.ps}, shows the angular velocities of the motor
and load. The clutch is engaged from time $t$ given by $0<t<15$; and
a unit input voltage is applied at time $t=0$. All initial conditions
are zero.
