$($PLEASE SOLVE USING FINITE ELEMENT ANALYSIS NOT PHYSICS, nodes $2$ and $3$ are fixed so that's the boundary condition. Please solve each for each element in the form k$=$EA$/$L$)$ The truss shown is made of Douglas fir of timbers of a $1cm1cm$ cross section, where

$L=1m.$ Determine:

Nodal displacements

Nodal reactions

Axial forces in bars

Stresses in bars

Material: Douglas fir

$E=13\mathrm{.}1$GPa
