A 1-ft-long rod is made from the material of Problem P5.11. By what amount must the rod be stretched from its original length for it to begin yielding?

Reference: Problem P5.11

Determine the elastic modulus and the yield strength for the material having the stress–strain curve shown in Figure P5.11. Use the 0.2% offset method.
