At 130°C, a bronze hoop 20 mm thick whose inside diameter is 600 mm just fits snugly over a steel hoop 15 mm thick. Both hoops are 100 mm wide. Compute the contact pressure between the hoops when the temperature drops to 20°C. Neglect the possibility that the inner ring may buckle. For steel, E = 200 GPa and α = 11.7μm/(m.°C). For bronze, E = 83 GPa α = 19 μm/(m.°C)
