Problem 2 From the tensile stress-strain behavior for the brass specimen shown in Figure below, determine the following: Stress (MPa) 500 Tensile strength 400 450 MPa (65,000 psi) 300 200 10³ psi MP 40 200 30 100 100 20 20 10 T 70 60 50 40 Yield strength 30 250 MPa (36,000 psi) 20 10 0.005 0.10 0.20 0.30 0.40 Strain Stress (10 psi) (a) The modulus of elasticity. (b) The yield strength at a strain offset of 0.002. (c) The maximum load that can be sustained by a cylindrical specimen having an original diameter of 12.8 mm (0.505 in.). (d) The change in length of a specimen originally 250 mm (10 in.) long that is subjected to a tensile stress of 345 MPa (50,000 psi).
