A composite bar consists of aluminum and steel is held by rigid supports as shown. At 57°C, an axial load of 220 kN is applied to the assembly. Determine the stresses in each of the component when the temperature is raised to 1120C. Based on laboratory results for steel, E = 210 GN/m², a = 24x10-6/ºC, and for aluminum, E = 70 GN/m², a = 11.8x10- 6/0C. STEEL Ø = 15cm? ALUMINUM Ø= 1Ocm² 220 kN -100 mm 150 mm

A composite bar consists of aluminum and steel is held by rigid supports as shown. At
57°C, an axial load of 220 kN is applied to the assembly. Determine the stresses in each
of the component when the temperature is raised to 112°C. Based on laboratory results
for steel, E = 210 GN/m?, a = 24x106/C, and for aluminum, E = 70 GN/m?, a = 11.8x10-
6/°C.
