Solid Mechanics , Classical Mechanics In the figure, solid copper rod with expansion coefficient αB = 165.10-7 1 / 0C It 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 of aÇ = 125.10-7 1 / 0C, and is combined with a rigid plate from the top so that they move together. It is combined with a rigid plate. System with temperature difference Δt = 80 0C Find the stresses that will occur in steel and copper when heated. Transcribed Image Text: Steel outer diameter
30 mm
