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.

At a temperature of 29.8 °C a 0.4-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 133.3°C, determine the change in length of the steel rod if L = 312.45 mm and M=201 mm. Round off the final answer to four decimal places. d - L M - B Aluminum A = 2000 mm² E = 75 GPa a = 23 x 10-6/°C Stainless steel A = 800 mm² E = 190 GPa α = 17.3 x 10-6/°C
