A straight strut of cross section 12.5 mm by 5 mm, and length 1 m is mounted on strut testing machine, and then loaded axially until it buckles. The fixtures at the strut ends are pin - joints. If the maximum central deflection of the strut at failure is 0.20 m, determine the yield stress of the strut. you are given the strut material stiffness of 210 GPa.
