Mechanical Properties

Question 1

List 9 mechanical properties

Answer 1

• strength
• hardness
• density
• durability
• toughness
• brittleness
• malleability
• ductility
• elasticity

Question 2

What is hardness?

Answer 2

The ability of a material to resist abrasive wear or scratching.

Question 3

What is density?

Answer 3

Density is mass per unit volume and often has an affect on other properties like hardness.

Question 4

What is durability?

Answer 4

Durability is the ability to resist this wear and tear.

Question 5

What is toughness?

Answer 5

The ability of materials to withstand sudden shocks or blows without breaking.

Question 6

What is brittleness?

Answer 6

Brittleness is the opposite of toughness where materials have little or no resistance to the application of force and break very easily.

Question 7

What is malleability?

Answer 7

Malleability is the ability of materials to be permanently deformed in all directions by the action of hammering, rolling or pressing.

Question 8

What is elasticity?

Answer 8

Elasticity is the ability to flex and bend when subjected to a force but regain normal shape when forces are removed.

Question 9

What is ductility?

Answer 9

Ductility is a materials ability to be cold deformed by being pulled or drawn into thinner sections or wires without breaking.

Question 10

What is strength?

Answer 10

Strength is the ability of a material to withstand an applied force without breaking or permanently bending.
