This document discusses material selection for a product. It asks questions about the product's function, how its components interact, how it is made, its target cost, and desired appearance. It then discusses evaluating materials based on their mechanical, thermal and electrical properties like Young's modulus, density, strength, and maximum service temperature for steel and polymers as potential materials.
