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.
