5. The bottom of a frying pan is made from three layers, each of 1 mm thickness. The top and bottom layer are made from stainless steel and the middle layer is made from copper. There are no internal stresses on the three layers at 25 °C. The frying pan is then heated to 170 °C. Compute the stress generated in the stainless steel and copper layers due to thermal expansion. Assume Estainless = 205 GPa, astainless = 13.9×10-6 1/K Ecopper = 104 GPa, acopper = 17.6×106 1/K
