Apply the rules of Prob. 16€“26 to the three-shaft system shown in the figure to create a motor shaft shish kebab.
(a) Show that the equivalent inertia Ie is given by
Ie = IM + IP + n2IP + IP/n2 + m2IP/n2 + IL/m2n2
(b) If the overall gear reduction R is a constant nm, show that the equivalent inertia becomes
Ie = IM + IP + n2 IP + IP/n2 + R2IP/n4 + IL/R2
(c) If the problem is to minimize the gear-train inertia, find the ratios n and m for the values of IP = 1, IM = 10, IL = 100, and R =10.
