What do materials undergoing plastic deformation do?
Change their shape when under a load, but return to their original shape when the load is removed.
Change their shape when under a load, but they remain permanently deformed when the load is removed.
Break or crumble rather than change their shape under a load.
Can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be more easily shaped when heated.
Tensile strength is
The ability of a material to resist a pulling, stretching force.

A pizza box is made from corrugated cardboard. Why is this the best choice for packaging pizzas?
It is weatherproof in case of rain when being delivered. The pizza will not go soggy.
The multi layers keep the heat in and make the card stronger and more supportive.
It is a very hard material and can resist dents when being transported.
The coating on this multicore wire is made from PVC (plastic). Why is this the best choice for coating the wires?
It is not a good conductor of electricity. There for covers the wires and makes sure they are insulated.
It is strong and cannot be broken when force is applied.
It is absorbent and will take take in any moisture and stop it getting to the wires inside?
It is fusible and can be made into a liquid.
The printed pattern on this fabric is conductive. What material would the printing ink need to contain for the light to work?
Wool as this is a textile and the circuit is painted onto a textile.
Acrylic as it softens with heat and this will allow it to be mixed with a paint.
A conductive metal, to allow the electricity to flow through the circuit.
Small pieces of aeroply so that the fabric will still be flexible after it is painted.
In order for a handle to be made fitting the form of a human hand comfortably. The best material choice would be:
Pine as it is reasonably strong and lightweight.
Wool as it is soft and absorbent.
Steel as it is durable and can resist wear and tear.
Polymorph as it can be moulded into different shapes easily.
This chair is made from acrylic. Why is this a good choice based on its properties?
It scratches easily so is not too hard.
It can be heated and shaped to fit the body as it is malleable.
It is shiny and looks good.
It comes in a range of colours to suit everyone.
This crib is a very unusual in its design. What would be a good material to make it from?
Aluminium as it could be bent into shape.
Corrugated cardboard as it is absorbent.
Wool as it is soft, warm and comfortable.
Aeroply as it can be formed into challenging shapes.
