A two-bar system has the configuration shown in the Figure Q1 below. The cross-sectional area for tension bar AB is 150 mm² and for tension bar BC is 100 mm². If the stress-strain curve for the bars is bilinear as shown, how much would each wire elongates due to the application of vertical force P = 21 kN. σ (MPa) 4 E₂ = 7.5 GPa 1 -7 120 MPa B E₁ = 14.5 GPa 3 P = 21 kN
