ACCURATE SOLUTIONS
Mechanical and nuclear engineering are generally considered to be this type of discipline: - correct
answer✔✔ Design engineering
Materials engineering is generally considered to be this type of discipline: - correct answer✔✔ Support
engineering
The activity sequence for manufactured products generally begins with: - correct answer✔✔ Design
The Met 2110 course will focus on this stage of the manufacturing sequence: - correct answer✔✔
Material selection
These materials exhibit both good strength and good ductility (formability) - correct answer✔✔ Metals
These materials are generally hard and strong, but also brittle. - correct answer✔✔ Ceramics
These materials offer good electrical and thermal conductivity. - correct answer✔✔ Metals
These materials typically have the lowest strength, but are light weight. - correct answer✔✔ Polymers
These materials can provide electrical & thermal insulation at high operating temperatures. - correct
answer✔✔ Ceramics
These materials are often called "plastics". - correct answer✔✔ Polymers
These materials would be the least suitable for use at elevated temperatures. - correct answer✔✔
Polymers
, In this type of bonding, the valence electrons are free to "wander" throughout the structure (high
conductivity). - correct answer✔✔ Metallic
This is the weakest of the four types of bonding. - correct answer✔✔ VanderWaals
Two different types of atoms (an electron donor and an electron receiver) are required in this type of
bonding. - correct answer✔✔ Ionic
The bonds between carbon-carbon and carbon-hydrogen (common within polymers) are of this type. -
correct answer✔✔ Covalent
Materials bonded by this type of bond can exhibit both high strength and high ductility. - correct
answer✔✔ Metallic
The restricted number of "neighbors" leads to directional bonding and low densities in this type of
bonding. - correct answer✔✔ Covalent
When a magnesium atom gives up two electrons to an oxygen atom, resulting in the formation of MgO,
the type of atomic bonding must be: - correct answer✔✔ Ionic
In this type of bonding, the bonding electrons are "captive to atoms" (low conductivity). - correct
answer✔✔ Ionic
In this type of bonding, the bonding is between molecules, not between atoms. - correct answer✔✔
VanderWaals
A collection of ordered points in space is called a ___. - correct answer✔✔ Lattice
The smallest volume of a lattice that retains all of its characteristics is called the: - correct answer✔✔
Unit Cell
