O c. inorganic materials
O d. Brittle
A wide variety of shapes can be produced by cold-forming and manufacturers have developed a wide range of products to meet specific applications.
Three materials X, Y, and Z are available for a certain usage. Any material selected must have a good
weldability. Tensile strength, stiffness, stability and fatigue strength are required with fatigue strength considered
being the most important and stiffness the least important of these factors. The three materials are rated as follows in
these factors.

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.
