PhysicsQ&A LibraryA tensile test specimen has a gage length = 3.0 in anddiameter 0.75 in. Yielding occurs at a load of 38,000 lb. Thecorresponding gage length 3.01 03 in (neglect the 0.2 percentyield point). The maximum load of 54,000 lb is reached at a gagelength 3.453 in. If the specimen necked down to a diameter0.645 in, determine the percent reduction in area (round to thenearest whole %).40Question
