Warm up, September 26-27

Some outdoor markers, such as those found in cemeteries, are expected to last for centuries. Based on you knowledge of materials engineering (Lesson 1), why has bronze, historically, been used for this purpose more often than stainless steel? Give at lease 3 reasons.

SUPPLEMENTAL Question:

Sometimes designs for products, and the materials from which they are made, persist primarily because users/consumers are accustomed to an established tradition. Give at least three examples of a product which uses a particular design/material in large part just because people are used to it. That is, even though an updated design or material might work better.
