A $5$ m$-$long cantilever beam with a $\backslash (2\backslash$mathrm$\{$~cm$\}\backslash$times $4\backslash$mathrm$\{$~cm$\}\backslash )($bxh$)$ cross section has a load of $100$ N applied at B and a $\backslash (25\backslash$mathrm$\{$~N$\}/\backslash$mathrm$\{$m$\}\backslash )$ distributed load applied to the $\backslash ($ A B $\backslash )$ section on the left as shown here. What is the maximum normal stress in MPa? The Correct Answer is around $93\mathrm{.}75$ MPa
