In a body-centered cubic structure, how many atoms are contained entirely within the unit cell?

• A. 1

• B. 2

• C. 4

• D. 8

Which crystal structure is typically the most brittle?

• Simple cubic

• Body-centered cubic

• Face-centered cubic

• Hexagonal close-packed

What is the primary role of a slip plane in a crystal lattice?

• It makes the material more brittle under load

• It allows atomic movement, enabling plastic deformation

• It blocks dislocations in the crystal structure

• It controls the material's density

If a material can easily resist wear and scratching, it has:

• High hardness

• High malleability

• Low density

• High ductility

How do you reverse work-hardening in a twisted copper wire?

• Twist in opposite direction

• Heat up the wire

• Work hardening cannot be reversed

• Stretch out the wire

What happens to a material during annealing?

• It becomes harder and less flexible

• It softens and relieves internal stresses

• It gains additional layers of atomic structure

• It loses ductility but gains strength
