    It is desired to evaluate the tensile properties of an aluminum alloy. A tensile test is performed using a standard cylindrical tensile specimen with a diameter of 12.8 mm and a gauge length of 50.800 mm. The gage length and final diameter of the sample are measured after the sample is removed from the testing machine. The gage length and the diameter of the necked region after the specimen was removed from the testing machine are 60 mm and 9...
