Question

A cylindrical specimen of stainless steel having diameter of 12.8 mm and a guage length of 50.88 mm(2.000in.) is pulled in tension. Use the load-elongation characterisitcs shown in the following table. Plot the data as engineering stress vs. engineering strain. Then compute the modulus of elasticity, yeild strength at a strain offset of 0.002, determine the tensile strength of this alloy, approximate ductility in percent elongation and the modulus of resilience.
