steel A aluminum 2 m- B 2m 9 m bronze C 3 m The assembly shown consists of a steel cylinder (E = 200 GPa, A = 150 mm2,= 12 um/m °C), an aluminum alloy cylinder (E = 70 GPa, A = 230 mm2, = 23 μm/m °C), and a hollow bronze tube (E = 100 GPa, A = 190 mm2, = 18 um/m °C) welded to the rigid bar at points A, B, and C, respectively. Initially, the system is stress-free. When the assembly is heated by 45°C, determine the normal stress (in MPa) in the bronze tube and the horizontal distance (in m) with reference to point A where the rigid bar tilts. Neglect the weight of the members. The answer should be: Obr= 8.9507 MPa, C, d= 4.6625 m

Another of the steel components manufactured by michael's company is steel railway track sections. Thecomponent has a length of 120m (at a temperature of -10°C) and is to be exposed to a temperaturerange of -10°C to 55°C. In order to calculate the gaps which need to be left between the sections michael'scustomer needs to determine the maximum length which each railway track section will expand to andmichael have been asked to carry out the calculation for them. michael have also been instructed to determinethe percentage change in volume and surface area when exposed to the same initial and finaltemperatures. The customer has informed him that the cross sectional profile of the railway track isrectangular and of breadth 14cm and height 32cm. Assume the coefficient of thermal expansion ofsteel is 12x10-6 /°C. Briefly discuss the changes that occur with in the steel as a result of the change intemperature.
A circular steel rod AB (diameter d1=15 mm, length L1=1100 mm) has a bronze sleeve (outer diameter d2 21 mm, length L2=800 mm) shrunk onto it so that the two parts are securely bonded (see figure). Calculate the total elongation δ (mm) of the steel bar due to a temperature rise ΔT=200oC. (Material properties are as follows: for steel, Es=210 GPa and αs=12x10-6/C; for bronze, Eb=110 GPa and αb=20x10-6/C.)

The assembly shown in the figure consists of an aluminum tube AB and a steel rod BC. The rod is attached to the tube through the rigid collar at B and passes through the tube. The cross-sectional area of the rod is 75 mm2 and the cross-sectional area of the tube is 400 + UV in mm2, where UV is 99. A tensile load of 80 kN is applied to the rod. Take Est = 200 GPa for the steel rod, Eal = 70 GPa for the aluminum tube. Determine: (a) the displacement of end C with respect to end B (i.e., the elongation of the steel rod), (b) the displacement of end B with respect to the fixed end A (i.e., the shrink of the aluminum tube), (c) the displacement of the end C of the rod (i.e., (a) + (b)).
