A steel bolt of diameter 10 mm passes through a brass tube of internal diameter 15 mm and external diameter 25 mm. The bolt is tightened by a nut so that the length of tube is reduced by 1.5 mm. If the temperature of the assembly is raised by 40°C, estimate the axial stresses the bolt and the tube before and after heating. Material properties for steel and brass are: Es=2×10' N/mm² a = 1.2x10 5/° C and E= 1×105 N/mm² -1.9×10-15°C

The rigid bar AC is supported by two axial bars (1) and (2). Both axial bars are made of bronze [E = 100 GPa; a = 18 × 10-6 mm/mm/ °C). The cross-sectional area of bar (1) is A1 = 184 mm2 and the cross-sectional area of bar (2) is A2 = 380 mm2. After load P has been applied and the temperature of the entire assembly has increased by 38°C, the total strain in bar (2) is measured as 1240 µɛ (elongation).

In the figure, a solid copper rod with an expansion coefficient α copper = 165.10-7 1/ºC 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 αsteel = 125.10-7 1/ºC, and is combined with 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 ºC. (Esteel=200 GPa, Ecopper=100 GPa)
What will be the stress induced in a steel bar when it is heated from 15°C to 60°C, all expansion being prevented? For mild steel, E = 210 GN/m2 and a = 11 x 10"6 per °C
Consider the simplified stress-strain curve of mild steel shown in the figure below. Only the strains as shown in the figure are known at the critical points. If the ultimate strength is 1.5 times the yield strength, the energy absorbed by this steel per unit volume up to the point U is: U Y S O: ɛ = 0 .F Y: ɛ = 0.002 Young's Modulus, E = 29,000 ksi S: ɛ = 0.02 U: ɛ = 0.1 F: ɛ = 0.15 Strain Stress (ksi)
