For each example in Figure $1\mathrm{.}17,$ determine the theoretical minimum part count. Also, establish the

part count when practical considerations are taken into account. In example b$,$ assume both box and

cover are die castings and, in example c$,$ assume that the purpose is to cover the hole in the base

plate.
