Bar (1) is steel [E = 219 GPa, a = 11.2 x 10-6/°C]with a cross-sectional area of A1 = 470 mm?. Bar (2) is an aluminum alloy [E = 74 GPa, a = 22 x 10-6/°C] with a cross-sectional area ofA2 = 280 mm?. The bars are unstressed when the structure is assembled. Assume L=790 mm, a= 310 mm, b=630 mm, c=790 mm, andP=44 kN.
