Properties Of Materials

Question 1

Ductility

Answer 1

Ability of a metal to deform by bending / stretching / twisting

Question 2

Malleability

Answer 2

Ability of a material to be permanently deforormed in all directions wothout it fracturing

Question 3

Hardness

Answer 3

Ability of a material to resist deformation, indentation or penetration

Hard materials can abrasion, drilling, impact, scratching and generao wear and tear

Question 4

Tensile strength

Answer 4

Amount of force and object can withstand when being pulled

Question 5

Compressive strength

Answer 5

The amount of ‘crushing force’ an object can withstand

The denser a material the greater its compressive strength

Question 6

Strength

Answer 6

Ability to withstand a force

Question 7

Elasticity

Answer 7

Ability to return to an original shape once the deforming force is removed

Question 8

Plasticity

Answer 8

Ability to be permanently deformed without breaking / fracture

Question 9

Answer 9

Ability to withstand sudden stress or shocks

Question 10

Brittleness

Answer 10

Inability to withstand sudden stress / shocks

Question 11

Durability

Answer 11

Ability to withstand deterioration over time

Question 12

Stability

Answer 12

Ability to resist changes in shape over time

Question 13

Stiffness

Answer 13

Ability to resist bending

Question 14

Density

Answer 14

Compactness of a material (mass per volume)

Question 15

Electrical / thermal conductivity

Answer 15

Ability to conduct electrical / thermal energy

Question 16

Size

Answer 16

Dimensions of a material

Question 17

Corrosion

Answer 17

Oxidisation of metals in the presence of air and water.

Can decrease the strength of metals / other mechanical properties

Question 18
