(uscs units) a tensile test specimen has a gage length = 2.0 in and diameter = 0.798 in. yielding occurs at a load of 31,000 lb. the corresponding gage length = 2.0083 in, which is the 0.2 percent yield point. the maximum load of 58,000 lb is reached at a gage length = 2.47 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 = 0.36 in2 , determine the percent reduction in area.
