An aluminum rod elastic modulus of 70 GPa yield strength of 40 MPa as shown in Fig a with circular cross section is subjected to an axial load of 10 kN Given the stress strain curve for a tensile test of this material is shown in Fig b determine 1 The approximate elongation increase in length of the rod when under the tensile load of 10 kN 2 If the specimen is unloaded the applied force being removed and then reloaded with 10 kN find the new total elongation as compared to the original before question 1 length YA AB d MPa BRERARS 50 40mile 40 30 20 10 600 mm 15 mm 400 mm 10 045 10 KN elastic in AB 10 11 0 001 Bc Opc plastic AB 0 01 AB 31 3 May 56 6 Mpsey p 56 6 31 4 0 0005 70x10 EBC from graph EBC 0 045 under load 0 mm EAE 400mm E
