page 1 Engineering 45 The Structure and Properties of Materials Spring, 2011 Problem Set No. 1 Problem 1: The following are general interest questions that address issues in materials technology. (a) The element silicon is far more abundant than iron and is widely used in structural materials such as silicate rocks and cement. However, it is rarely used in advanced engineering structures (e.g., automobiles, airplanes, machinery) and is almost never used as a structural material in its elemental form. Why? (b) Even though aluminum is more abundant than iron in the earth’s crust, it is produced in much smaller quantities than iron, and is less commonly used even in structures such as refrigerators and filing cabinet cases where its lower density might offer an advantage. Why? (c) Stainless steels are commonly used in devices that go into the human body. What advantages might they offer over typical structural steels and many non-ferrous materials? (d) Plastics and other polymeric materials are expensive with respect to steel, and
