Problem $07\mathrm{.}037-$ Determine the critical speeds of a shaft of varying diameters

The steel shaft shown in the figure carries two gears. Estimate the first critical speed due to the loads, the shaft's critical speed without the loads, and the critical speed of the combination. All the distances shown in the figure are in inches.

Problem $07\mathrm{.}037.$b $-$ The ratlo of $\backslash ($ M $/$ I $\backslash )$ at varlous points along the shaft for unit loads

Consider $\backslash ($ w$\_\{1\}=1\backslash$mathrm$\{$lbf$\}\backslash )$ and $\backslash ($ w$\_\{2\}=0\backslash$mathrm$\{$lbf$\}\backslash ).($Round the final answers to four decimal places.$)$

Add the missing values of $\backslash ($ M $/$ I $\backslash )$ to the table shown below.

The missing values of $\backslash ($ M $/$ I $\backslash )$ are given in the following table:
