Q1

In the aerospace industry, the material cost is small in relation to the total fabricated cost of the material. If we assume approximately 10% of the total value of a pound saved on a sattelite may be spent on raw material, how much can we spend (in dollars per pound) on raw material?

Q2

Using the result of the previous question, which of the following materials can be justified for use in fabrication of a sattelite if a large majority of the sattelite will comprise the material selected?

nickel-based superalloys

silver

palladium

gold

high-strength composites

Q3

Based on the analysis of this section, at most approximately $.20/lb can go toward raw material cost in the fabrication of rail and ship transit carriers. What is the most expensive material that is feasible in the fabrication of the structural components in this sector?

wood

concrete

carbon steel

plastic
