copper st-iron 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 = 35 kN/mm², E3 120 kN/mm², a 1.3 x 10-5/°C, az 1.8 x 10-5/°C, α3 1.7 x 10-5/°C. = = 40 mm 0. 250 mm 6=80 mm 350 mm Figure 6 = 120 mm Ⓡ3 550 mm
