Discuss theprimary properties of FRP, its current and potential of future applications.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.If an SFRS has an R-factor of 5 and an overstrength factor (Ω o) of 3, what is its approximate ductility capacity?
- Alcoa Corporation (from Aluminum Company of America) is an American industrial corporation. It is the world's sixth largest producer of aluminum, with corporate headquarters in Pittsburgh, Pennsylvania. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling. In a casting R&D trial of a certain aluminum alloy which performed in Alcoa Co, Ltd., by using a particular sand mold, it took 5 mins for a rectangular-prism shaped casting part (length=6 in, width=8 in, height=10 in) to solidify. Calculate the minimum solidification time of the cylindrical riser so that the riser will be effective by using Chvorinov's Rule. Use the following table for the dimensions of the cylindrical-shaped riser. diameter=10 in height= 8 in n (constant) = 2If the final lenght of materials is 10.1mm and its ductility is measured as 1 % in terms of elongation .what is its initial lenghtSelect a suitable material for aircraft wing. 4) Fine sereening 5) Final selection or Identification 6) Re-iterations
