$(1)-$ Select the optimum structural diagram for $18$ speed gear box?

Solution $*$

:$\text{'}18=3+3+2-q=2"$No$.$of equal transmission group"

:$.,m=3$ transimission group.

Nai of shaft $=3+1=4$ shafts.

No$.$ i structural duagrams $=\frac{m!m!}{q!}=\frac{3!3!}{2!}=\frac{36}{2}=18$ structure:

$No.of$ gears $=(3+3+2)**2=3*2+3**2+2**2=16$ gears
