Materials Science and Engineering
(Prelims) Exam With 100% Correct
Answers
Materials Science - correct answers ✔✔involves investigating the relationships that exist
between the structures and properties of materials.
Materials Engineering - correct answers ✔✔is designing or engineering the structure of a
material to produce a predetermined set of properties.
Subatomic Structure - correct answers ✔✔involves electrons within the individual atoms and
interactions with their nuclei.
Structural Realm - correct answers ✔✔contains large groups of atoms that are normally
agglomerated together is termed microscopic.
Structural Elements - correct answers ✔✔internal component that may be viewed with the
naked eye are termed macroscopic.
Property - correct answers ✔✔is a material trait in terms of the kind and magnitude of response
to a specific imposed stimulus.
Materials Scientist - correct answers ✔✔is a person who studies and analyzes the chemical
properties and structure of different man-made and natural materials.
Classification of Materials - correct answers ✔✔metals, ceramics and polymers; in addition,
composites and advanced materials.
, Metals - correct answers ✔✔materials in this group are composed of one or more metallic
elements and often also nonmetallic elements in relatively small amounts.
Ceramics - correct answers ✔✔are compounds between metallic and nonmetallic elements.
They are most frequently oxides, nitrides and carbides.
Polymers - correct answers ✔✔includes familiar plastic and rubber materials. Many of them are
organic compounds that are chemically based on carbon, hydrogen and other nonmetallic
elements.
Composites - correct answers ✔✔composed of two or more individual materials which come
from metals, ceramics or polymers.
Fiberglass - correct answers ✔✔one of the most common and familiar composites in which
small glass fibers are embedded within a polymeric material.
Carbon Fiber-Reinforced Polymer (CFRP) - correct answers ✔✔carbon fibers that are embedded
within a polymer. These materials are stiff and stronger than the glass fiber but they are more
expensive.
Advanced Materials - correct answers ✔✔these materials are used in high-technology
applications like devices operating under intricate and sophisticated principles.
Semiconductors - correct answers ✔✔have electrical properties that are intermediate between
the electrical conductors and insulators.
Biomaterials - correct answers ✔✔are employed in components implanted into human body for
replacement of diseased or damaged body parts.
