Problem $3$: Solve Problem $44$ from the Bending chapter in the e$-$textbook.

If $\backslash (\backslash$mathrm$\{$M$\}=10\backslash$mathrm$\{$kip$\}\backslash$cdot $\backslash$mathrm$\{$ft$\}\backslash ),$ determine the maximum bending stress in the beam. $\backslash (\backslash$mathrm$\{$I$\}=(1/12)\backslash$mathrm$\{$bh$\}^\{3\}\backslash ).$ To account for the missing material in the middle of the cross section, subtract the inertia calculated for the middle of the cross section using the inner dimensions from the moment of inertia calculated using the outer dimensions.
