The truss structure is shown below given the structure stiffness matrix K$.$ The horizontal concentrated load acting on node $2,$ Qx is $8\mathrm{.}6$ kN and the vertical concentrated load acting on node $2,$ Qy is $9\mathrm{.}7$ kN$.$ AE is constant for all members.

Please use the matrix method to determine the displacements at nodes $2$ and $3$ and the internal force in Member $1.$
