2.4a Material Properties

Ability of a material to plastically deform without breaking ie to be drawn into wires is

• ductility

• malleability

• brittleness

• resilience

Tendency for materials to break without undergoing any plastic deformation is

• ductility

• malleability

• brittleness

• resilience

Measure of the amount of energy stored in a material before failure/breaking is

• ductility

• malleability

• toughness

• resilience

The ratio of force to extension (ie force divided by extension) is

• ductility

• malleability

• toughness

• stiffness

The ability to spring back into shape is

• ductility

• resilience

• toughness

• stiffness

The ability to withstand repeated stress cycling is

• endurance

• resilience

• toughness

• stiffness

The ability to resist surface abrasion is

• endurance

• resilience

• toughness

• hardness

The ability to undergo deformation in compression before failure is

• ductility

• malleability

• brittleness

• resilience

The most ductile material is

• A

• B

• C

• D

Answer explanation

It is C as it undergoes the most plastic deformation (it extends more than the others)

The strongest material is

• A

• B

• C

• D

Answer explanation

It can withstand the highest stress before failure.
