FEM: Frames in plane stress $-$ Problem $4\mathrm{.}2$

The frame of the figure is charged at nodes $2$ and $3$ and the resulted deflections and slopes are shown in the table. Formulate the equations and calculate the shear forces $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$mathrm$\{$y$\}\}\backslash )$ and bending moments M at element $3.$

Calculate the axial force in element $3.$V $$v $$v $$s $()3,\backslash (\backslash$mathrm$\{$El$\}=1000\backslash$mathrm$\{$Nm$\}^\{2\},\backslash$mathrm$\{$EA$\}=10^\{7\}\backslash$mathrm$\{$~N$\},\backslash$mathrm$\{$~L$\}=1\backslash$mathrm$\{$~m$\}\backslash )$ o$$va$$ P $$ou $3.$

Note: the values in the table are in the absolute system
