Shown is the stress-strain curve developed from the tension test of a metal alloy bar. The specimen used to develop the stress-strain curve has a round cross-section with a diameter of d = 7 mm and a gauge length of L = 370 mm. Determine the load that must be applied to the specimen to stress the specimen to it's 0.2% offset yield. Express your answer in kN to the nearest whole kN. Your written solution must also include the length of the specimen when stressed to the 0.2% offset yield stress. σ (MPa) 700 600 500 400 300 200 100 0 0.02 0.04 0.06 0.08 0.10 0.002 0.004 0.006 0.008 0.010 € (mm/mm) P d

• Bars (1) have a cross-sectional area of A₁ = 0.65 in.2 and a length, L₁= 7 ft. • Bars (1) are made of cast iron with an elastic modulus of E₁ = 24,000 ksi, a coefficient of thermal expansion, a₁ = 12.3 x 10-6/°F and yield strength of oy = 120 ksi. • Bar (2) has a cross-sectional area of A₂ = 1.45 in.² and a length, L₂ = 5.5 ft. • Bar (2) is made of stainless steel with a coefficient of thermal expansion, a₂ = 10.6 × 10-6/°F. • The stress-strain diagram provided below presents the results of the stainless steel's (i.e., Bar (2)) bar tension test. • There is a gap of A = 0.1 in. in the connection at B and a = 3 ft. • All bars are unstressed before a load P = 12 kips is applied and the temperature increases by AT = 40°F.
