6 A steel pipe with a 50 mm outside diameter and a 43.75 'mm inside diameter surrounds a solid brass rod 37.5 mm in diameter as shown. Both materials are joined to a rigid cover plate at each end. The assembly is free to expand longitudinally. The assembly is stress free at a temperature of 27°C. For steel, Young's modulus is 200 GN/m², and the coefficient of linear thermal expansion is 11.7x10-6 1/°C. For brass, Young's modulus is 93.33 GN/m², and the coefficient of linear thermal expansion is 1.872 x 10-5 1/°C. What is the stress in the steel tube when the temperature is raised to 121°C? brass rod (solid) 37.5 mm diameter steel tube 50 mm outside diameter 43.75 mm inside diameter

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.

In each case assume that the specimen begins at 845°C (1550°F), and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure.
