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

Question 4 A steel rod of 20 mm diameter passes centrally through a copper tube of 50 mm external diameter and 40 mm internal diameter. The tube is closed at each end by rigid plates of negligible thickness. The nuts are tightened lightly home on the projecting parts of the rod. If the temperature of the assembly is raised by 50°C, calculate the stresses developed in copper and steel. Take E for steel and copper as 200 GN/m² and 100 GN/m² and a for steel and copper as 12x 10-6 per °C and 18 x 10-6 per °C.
A cylindrical pressure vessel is made by shrinking a brass shell over a mild steel shell. Both cylinders have a wall thickness of 6 mm. The nominal diameter of the vessel is 750 mm and is to be used in all calculations involving the diameter. When the brass cylinder is heated 50°C above room temperature, it exactly fits over the steel cylinder which is at room temperature. What is the stress in the brass cylinder when the composite vessels cool to room temperature? E for steel=200 GPA E for brass = 100 GPA a for steel = 12 x 10"/C a for brass = 19 x 106/°C Wrong answers will be downvoted
