:. Professor Meletis Louisiana State University Mechanical Engineering Department ME 2733 Materials of Engineering Homework Assignment #4 (due: Tuesday, March 16, 2004 ) I. The following load versus extension curves were obtained from tensile tests of two wires A and B, both 10 inches long and 0.1 in2 in cross sectional area. For Material A calculate: (a) the elastic modulus; (b) the yield strength and ultimate tensile strength;
