A tensile test specimen has a gage length = 2.0 in and diameter = 0.798 in. Yielding occurs at a load of 32,000 lb. The corresponding gage length = 2.0090 in, which is the 0.2 percent yield point. The maximum load of 60,000 lb is reached at a gage length = 2.72 in. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage length of 2.62 in, determine the percent elongation. (e) If the specimen necked to an area = 0.38 in2, determine the percent reduction in area
