Aluminum alloy 2024-T3 (T3 temper designation) is reported to have an elastic modulus of 72.4 GPa, yield strength of 345 MPa, and Poisson's ratio of 0.33 [Appendix B, 10e, eText]. Consider a specimen of this alloy with a width of 20 mm (square cross-section) and a gauge/initial length of 150 mm that is deformed in tension to a load of 40,000 N, assuming purely elastic deformation. a) Given the specified information, indicate whether it is reasonable to assume a purely elastic deformation, and briefly explain why or why not. b) Calculate the expected change in cross-sectional area (in mm²), AA (A40kN – Ao).
