Topic 1 - Material Properties Flashcards
What is hardness
The resistance a material has to cutting and surface indentations
What is toughness
The amount of energy a material can absorb without breaking. This is the opposite to brittleness. We measure a materials ability to absorb shock
What is malleability
The amount of hammering, pressing and shaping a material can take without breaking
What is ductility
The length that a material can be stretched without breaking
What is elasticity
The length that a material can be stretched and return to its original length when released
What is density
A materials mass in relation to its size
What is strength
The measure of how a material withstands a heavy load without breaking
What is resistance to moisture
A materials ability to prevent liquid and moisture permeating its surface
What is thermal conductivity
How easily heat energy can pass through material
What is electrical conductivity
How easily electrical energy can pass though a material
What is absorbency
A materials ability to soak up and retain liquid, heat or light
What is fusibility
How easily a materials state can be altered to become a liquid
What are some examples of compression forces
Standing on drinks can and squashing it
Pushing forces that squeeze an object
What are some examples of tension forces
A rope in tug of war competition as each side tries to pull the other side
Causes an object to be pulled apart
Causes an object to be stretched
What are some examples of torsion forces
Twisting a screw cap off the top of a bottle
Twisting forces that are applied to an object
Drive shafts of a car
