In the figure, a solid copper rod with an expansion coefficient αB = 165.10-7 1 / ° C is 20 mm in diameter. It is placed in a steel pipe with an outer diameter of 30 mm with an inner diameter of 2 mm larger than this bar and an expansion coefficient αÇ = 125.10-7 1 / ° C, and is joined by a rigid plate from the top so that they move together. Find the stresses that will occur in steel and copper when the system is heated with a temperature difference of Δt = 80 ° C. (EÇ = 200 GPa, EB = 100 GPa)
