2) 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. When the applied load is 45 KN, the new diameter of the specimen is 12.48375 mm. Compute the shear modulus (Gal) for the aluminum. σ (MPa) 500 [1 0.00614 € (mm/mm)
