$2.$ The $10-$meter$-$long beam below is supported at $\backslash ($ A $\backslash )$ by a fixed pin and at $\backslash ($ B $\backslash )$ by a roller pin. The beam is loaded, as shown, where $\backslash (\backslash$mathrm$\{$w$\}=100\backslash$mathrm$\{$~N$\}/\backslash$mathrm$\{$m$\}\backslash )$ and $\backslash (\backslash$mathrm$\{$P$\}=2000\backslash$mathrm$\{$~N$\}\backslash ).$ Draw the shear force and bending moment diagrams and identify the largest absolute shear stress and largest absolute bending moment in the beam.
