$4.$ For the beam and loading shown, $\backslash ($ P $\backslash )\backslash (=36\backslash )$ kips. Draw the shear and bending$-$moment diagrams and label key values appropriately. Determine the maximum normal stress due to bending. Know that for a W$12\backslash (\backslash$times $40\backslash )$ beam, $\backslash (\backslash$mathrm$\{$S$\}=51\mathrm{.}5\backslash$mathrm$\{$in$\}^\{3\}\backslash ).$ HINT: Think back to frames in terms of how you might solve for the unknown vertical reaction forces.
