Determine the elongation of the square hollow bar when it is subjected to the axial force P3 100 kN. If this axial force is increased to P- 360 kN and released, Find the permanent elongation of the bar. The bar is made of a metal alloy having a stress-strain diagram which can be approximated as shown in figure.
