The motion characteristics of piston shown in Fig. 8.27 show that when inertia
decreases, i.e., I value increases, the period of fluctuation of piston velocity
decreases, i.e., the frequency of variation of velocity increases. And the piston
velocity amplitude is larger than the other two cases (as shown in Figs. 8.24 and
