ANSWERS
T or F: It's been said that at the heart of every engineering problem there exists a
materials challenge - Answers - True
Choose the best answer from among the choices listed: "Materials engineering involves
___________" - Answers - Designing or engineering the structure of a material to
produce a predetermined set of properties
"Why is BME350 required in the undergraduate BS in BME curriculum"? - Answers -
materials are an integral part of most all healthcare engineering
Christian Thompson said there are "quanta" of materials technology that enabled
"leaps" in societal advances. Choose all such "quanta" that Thomson referred to in his
1836 publication - Answers - Stone age, Bronze Age, iron age
Which of the three ages cited by Thomson in 1836 endured the longest? - Answers -
Stone age
Choose all such materials potentially use by inhabitants of the longest enduring
materials epoch, i.e. the Stone Age - Answers - Hair, fur, clay, animal skins, tendons &
ligaments, stone, bone, wood
Tendons were among the materials used during the Stone Age. Select from the list
below all applications of tendons during this epoch. - Answers - Energy storage for
weapons, fastening materiasl
Stone Age materials remain an important part of modern life. Choose all materials used
in the Stone Age that remain in use today - Answers - Bone, horns & antlers;
stones(e.g. flints) for fire starting; wood for home framing; clay; decorative rocks;
stone(for sharpening knives); animal hair
What "revolutionary" material began to displace wood, clay, hair, tendon, flint, stone,
etc. used in the Stone Age? - Answers - Bronze
How many different elements were primarily used to make bronze (the superior metal
that displaced Stone Age materials) - Answers - 2
Choose the key elements which, when alloyed together (neglecting minor constituents),
comprise bronze? - Answers - Sn, Cu
, Bronze offered a remarkable materials advance for society because it could be readily
shaped into enduring useful objects. What materials processing methods were used to
shape objects made of bronze? - Answers - Hammering, casting
Bronze offered a substantial advantage for fabricating items needed by society. In
addition to the ease of fabrication to shape by casting and hammering, what other
feature of bronze made it particularly useful to society? - Answers - Corrosion
resistance
Bronze was an important materials because it was easy to shape by hammering and
casting and offered tremendous corrosion resistance. What is the basis for bronze's
corrosion resistance? - Answers - Spontaneous formation of an oxide layer
Bronze has superior corrosion resistance, low friction coefficient and is durable in
corrosive environments. These properties result in extensive use of bronze for
applications that continue to the present day. These applications include: - Answers -
Household hardware, marine hardware, sculpture, bearings in machinery, bushings,
coinage
What material largely displaced bronze in society? - Answers - Iron
Why did Iron largely displaced bronze in society? - Answers - Abundance in earth's
crust, superior control of hardness, economics of processing
Steel is an important material resulting from the Iron Age. Steel is chiefly made by
alloying iron with what other metal - Answers - C
Iron ore treated with reducing agent to convert iron oxide to pure Fe. What process is
used to transform iron ore to pure iron? - Answers - Smelting
Structural steel is ubiquitous in modern society. Reasons for this include the ready
engineering control of material strength to meet in-service requirements. Choose all
methods used to control the strength of structural steel: - Answers - Alloying, processing
What are the biomedical applications of unalloyed iron? - Answers - None of the choices
Ceramic materials consist of a metal and a non-metal. Choose all features of ceramics
that offer advantages to biomedical engineers: - Answers - Hardness, corrosion
resistance, low wear, low friction, aesthetics
The largest disadvantage of ceramics used for biomedical applications is: - Answers -
Mechanical brittleness
What's a "mer" when used to describe an aspect of a material? - Answers -
Fundamental unit of a polymer structire
