$4\mathrm{.}24A1212cm$ square plate of titanium $(E=115$GPa$)$ is subjected to normal

tensile forces of $15$ kN and $20$ kN on the top and right edges as shown in

Figure P$4\mathrm{.}24.$ The thickness of the plate is $5$ mm $,$ and the left and bottom

edges of the plate are fixed. Find the normal strain and deformation of the

plate in the horizontal and vertical directions.
