Part 1 - Materials and their Applications

Question 1

Density

Answer 1

The mass of the material in a standard volume of space

Question 2

Fusibility

Answer 2

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

Question 3

Magnetism

Answer 3

The natural force between objects that causes the material to attract iron or steel.

Question 4

Corrosion resistance

Answer 4

The ability of the material to withstand environment attack and decay

Question 5

Electrical conductor

Answer 5

Allows the flow of electrical current though the material. A good conductor gives very little resistance to the flow of charge

Question 6

Compressive Strength

Answer 6

the ability to withstand being crushed

Question 7

Tensile strength

Answer 7

the ability to withstand being stretched

Question 8

Bending strength

Answer 8

ability to withstand forces bending the material

Question 9

Shear strength

Answer 9

ability to withstand sliding forces with parralel forces

Question 10

Torsional strength

Answer 10

ability to withstand twisting forces from an applied torque

Question 11

Hardness

Answer 11

ability to resist abrasive wear such as scratching or cutting.

Question 12

Toughness

Answer 12

ability to absorbe impact force without fracture

Question 13

Plasticity

Answer 13

the ability to be deformed and retain the deformed shape

Question 14

ductility

Answer 14

ability to be made into a wire or something similar

Question 15

malleability

Answer 15

the ability to withstand compression without cracking

Question 16

elasticity

Answer 16

ability to be deformed and return to its original shape.

Question 17

thermal expansion

Answer 17

increase in volume after heat applied
