BME 350 EXAM 1 (CH 1-4) QUESTIONS WITH VERIFIED
ANSWERS
What is material science? - Answers - a branch of science that studies fundamental
relationships between the structure and properties of materials
What is materials engineering? - Answers - field of engineering involving the design or
engineering the structure of a material to produce a predetermined set of properties
What is the process of smelting? - Answers - a process involving charcoal to generate
carbon monoxide in the production of iron
The Mars probe is currently on the surface of Mars drilling to obtain soil and rock
samples and send them back to earth. Is this related to the archeological details briefly
mentioned at the beginning of the semester? - Answers - is is related because the
history of materials provides information about the development of peoples and planets
What advantages does bronze offer for materials engineers today? Choose all that
apply from the list below: - Answers - bushings & bearings
coinage
marine hardware
List all of the advantages of elemental metals to the field of engineering. - Answers -
economical due to abundance in earth's crust
Correct! conduct heat and electric current
Correct! favorable mechanical properties, especially ductility
Correct! properties can be controlled with alloying with other elements
While ancient societies were characterized for the materials they used to make tools
and weapons, what material might a future archeologist most closely associate with
American society in the early 21st Century? - Answers - silicon
The materials engineer investigating what elements will bond with what other elements
will likely first consider: - Answers - valence electrons of materials
Hydrogen bonding is more likely to be found in a container of: - Answers - water
Rank the order of chemical bond strength from weakest (left) to strongest (right): -
Answers - van der Waals, hydrogen, metallic, covalent, ionic
Why is chemical bonding so important to the materials engineer? - Answers - bonding is
a major determinant of material type
