$**$I DO NOT WANT A MATLAB CODE$**$ A $2$D truss structure, with pinned joints and supports, is loaded as shown in the figure where applied forces are $F_{2}69\mathrm{.}01kN$ and $F_{x}36\mathrm{.}28kN.$ The structure has a Young's modulus of $E=210{10}^{9}Pa,$ the cross sectional areas of the first and third elements are, $A_1=A_3=2\mathrm{.}5c{m}^2$ and the product $A_n\frac{E_n}{L_n}$ is constant for all the

elements. Calculate the deflection of the second node. Give your answer in mm $.$
