An aluminium pipe is rigidly clamped to the face of a concrete building. On a hot day the face of the building in direct sun rises to 80°C. Knowing that the expansion of the aluminium is greater than that of concrete, aluminium has a = 22.5 x 10-6/°C and E= 75 GPa, concrete has a = 9 x 10-6/°C. What is the value of the stress if the original clamping was done on a day when the temperature was 20°C? Explain your result.
