Extracted text: Determine the stress in each of the two vertical rods if the temperature rises 50 *C after the load P=75 KN is applied. Neglect the deformation and mass of the horizontal bar AB. Use Ea = 75 GPa, as=23.0 um/m-°C, Aa = 850 mm2, Es = 210 GPa, as = 11.9 um/m°C and As = 650 mm² . Steel Aluminum 2.5m 3m B 3m 3m 3m 75 kN
