A bar made of structural steel having the stress-strain diagram shown in the figure has a length of 9 in. The yield stress of the steel is 39 ksi, and the slope of the initial linear part of the stress-strain curve (modulus of elasticity) is 30000 ksi. The bar is loaded axially until it elongates 0.20 in., and then the load is removed. Calculate the final length and show how does of the bar compare with its original length? Note: Use SI Units
