b$)$ Determine the actual dimensions to be provided for a shaft and hole of $90$ mm size

for $\frac{H_8}{e_9}$ type fit. Also design general purpose GO and NO$-$GO gauges for the same.

$1\mathrm{.}90$ mm falls in the diameter step of $80-100$

$i=0\mathrm{.}45(D{)}^{\frac{1}{3}}+0\mathrm{.}001(D)$ microns

Fundamental Deviation for $\text{'}{e}^{\text{'}}$ shaft $=-11D^{0\mathrm{.}41}$

$IT8=25$i and $IT9=40i$
