MSE2034 Homework #5 Due Thursday, February 25 2 pts each, Maximum Score = 14/14 1) Given the following stress-strain data [for a “6061-T6” aluminum alloy], construct a reasonable stress -strain curve for this material, to scale, and label the important features of it. Show any necessary calculations, and justify any estimates or guesses you make. You may assume that the qualitative appearance of the curve is the same as those shown in Figs 6 .11- 6 .14. E = 69 GPa (Modulus) σ Y = 276 MPa (Yield strength) σ T = 310 MPa (Tensile strength) ε F = 0.175 (Failure strain) 2) Material constants for annealed pure copper are given in Tables 6.1, 6.2, and 6.4. Using this information, answer the following: (a) By how much could a 100 mm long copper rod be stretched in tension without creating any permanent deformation, in terms of both strain and absolute length? (b) If exactly the maximum amount of elastic tensile strain [from part (a)] is introduced into a 100 mm rod with radius of 5 mm, how much will its radius have changed at the end of the process? (c) Assuming that Eqn
