A cоpper bаr with а rectаngular crоss sectiоn is held without stress between rigid supports (see figure). Subsequently, the temperature of the bar is raised to 50°C. (Assume alpha = 17.5 X 10-6/°C and E = 120 GPa.) Question 6.1: Determine the stress due to temperature increase. [enter solution in MPa - whole number]
