At 22.3 C, there is a gap Delta = 0.2 mm between the lower end of the bronze bar and the rigid slab supported by the two steel bars as shown. Neglecting the mass of the slab, determine the stress (MPa) in each rod when the temperature of the assembly is increased to 102.3 C. For the bronze rod, A=723 mm^ 2, E =83x10^9 N/(m^2), and the a=18.23 um/(mC). For each steel rod, A=623 mm^2, E = 200x10^9 N/(m^2), and the a = 11.23 um/(mC).
