The stress-strain diagram for a material can be approximated by the two line segments
Chapter 13, Problem 13-75(choose chapter or problem)
The stress-strain diagram for a material can be approximated by the two line segments shown. If a bar having a diameter of 80 mm and a length of 1.5 m is made from this material, determine the critical load provided the ends are pinned. Assume that the load acts through the axis of the bar. Use Engesser’s equation.
