Part A The elastic portion of the tension stress-strain diagram for an aluminum alloy is shown in the figure. The specimen used for the test has a gauge length of 50 mm and a diameter of 12.5 mm. The shear modulus is Gal = 28 GPa. (Figure 1) If the applied load is 55 kN, determine the new diameter of the specimen.
