Ecopper 75 GPa and Ecast-iron 175 GPa. = b) A composite bar is fixed between two supports (Figure 6). If the temperature of the bar is raised from 15°C to 85°C, find the stresses induced in each rod by assuming (a) if the supports don't yield and (b) if the support yield by 0.15 mm. Take E₁ = 210 kN/mm², E₂ = 35kN/mm², E3 = 120 kN/mm², a₁ = 1.3 x 10-5/°C, a2 = 1.8 x 10-5/°C, a3 = 1.7 x 10-5/°C. $ = 120 mm $= 40 mm 1...... 250 mm - 80 mm = 2 350 mm Figure 6 3 550 mm
