Mechanical properties

Property matchup
Match each mechanical property with an appropriate description.
The mechanical properties are:
•	Hardness
•	Toughness
•	Elasticity
•	Brittleness
•	Ductility
•	Plasticity
•	Malleability
•	Strength.
The descriptions are:
•	Resistance to the load that will just cause fracture
•	Ability to be drawn out in the direction of its length
•	Material deforms with loading and returns to original shape when loads are removed
•	Material retains its deformed shape when load is removed
•	Material can be worked into various shapes
•	Material will break without elongation
•	Resistance to fracture by repeated bending or twisting
•	Degree of resistance to indentation or abrasion.

The correct answers are:
•	Hardness - Degree of resistance to indentation or abrasion
•	Toughness - Resistance to fracture by repeated bending or twisting
•	Elasticity - Material deforms with loading and returns to original shape when loads are removed
•	Brittleness - Material will break without elongation
•	Ductility - Ability to be drawn out in the direction of its length
•	Plasticity - Material retains its deformed shape when load is removed
•	Malleability - Material can be worked into various shapes
•	Strength - Resistance to the load that will just cause fracture.
