Properties

Question 1

Compressive strength?

Answer 1

The ability to withstands being crushed or shortened by pushing forces

Question 2

Tensile strength?

Answer 2

The ability to resist stretching or pulling forces

Question 3

Hardness?

Answer 3

The ability to withstands abrasive wear such as scratching, surface indentation or cutting

Question 4

Toughness?

Answer 4

The ability to absorb impact force without fracture

Question 5

Bending strength?

Answer 5

The ability to resist forces that may bend the material

Question 6

Shear strength

Answer 6

The ability to resist sliding forces on a parallel plane

Question 7

Torsional strength?

Answer 7

The ability to withstands twisting forces from applied torque or torsion

Question 8

Plasticity?

Answer 8

The ability to be permanently deformed and retained deformed shape

Question 9

Ductility

Answer 9

The ability to be drawn out under tension, reducing the cross-sectional area without cracking

Question 10

Malleability

Answer 10

The ability to withstands being crushed deformation by compression without cracking

Question 11

Elasticity?

Answer 11

The ability to be deformed and then return to original shape when force is removed

Question 12

Electrical conductor?

Answer 12

Allows the flow of electrical current through the material

Question 13

Electrical insulator?

Answer 13

Does not allow the flow of electricity through the material

Question 14

Thermal conductor?

Answer 14

Allows the transfer of heat energy through the material. A material with high thermal conductivity allows the transfer of heat to occur quickly across the material

Question 15

Thermal insulator?

Answer 15

Prevents the transfer of heat through the material

Question 16

Thermal expansion?

Answer 16

The increase in material volume in response to a heat input

Question 17

Opaque?

Answer 17

prevents light from travelling through

Question 18

Translucent?

Answer 18

Allows then light through but diffuses the light so that objects appear blurred. Frosted glass is an example of a translucent material

Question 19

Transparent?

Answer 19

Allows light to pass through easily which means you can see clearly through the material

Question 20

Density?

Answer 20

The mass of the material in a standard volume space

Question 21

Magnetism

Answer 21

the natural force between objects that cause the material to attract iron or steels

Question 22

Fusibility?

Answer 22

the ability of the material to be fused or converted from a solid to a liquid or a molten state, usually by heat. Good fusibility is an essential property for a metal being cast

Question 23

Corrosion

Answer 23

The ability of the material to resist environmental attack and decay
