a. Which of the five materials is more ductile? Why?
b. Which material has the lowest stiffness? Why?
c. For a given small stress (below the yield strength), which material will have the smaller amount
of elastic deformation? Why?
d. If the same small stress (below the yield strength) is applied to all materials, which material will
experience the largest plastic deformation? Why?
e. Which material has the highest hardness?
e. A cylindrical rod 20 inches long, having a diameter of 0.505 inches, is to be subjected to a
tensile load. The rod may not experience plastic deformation or a change in length of more than
0.03 inches when a load of 10050 pounds is applied, which material is a possible candidate?
Why?
