For the two$-$dimensional truss shown below, determine:

the nodal displacements

the element axial stress

the individual element nodal forces

Members $(1)$ and $(2)$ each have a length of $2$ m $.$ Each member has a cross$-$sectional area of

$80m{m}^2$ and a modulus of elasticity of $200$ GPa $.$ The applied forces are $F_A=2kN$ and $F_B=$

$3$ kN $.($Ignore the possibility of buckling in members under compression.$)$
