To make electrical wire the material used must have what properties?

• Brittle and strong

• Ductile

• Hard

• Maluable

What material are urinals made from?

Oil Rigs work in harsh salty environments, why are they constructed of carbon steels that can rust and not stainless steel?

• The cost of manufacture and repair is the cheapest overall option

• The metal will not rust in the sea.

• Carbon steel has good thermal properties for the cold environment

• Carbon steel is ductile and will withstand the forces of the waves hitting it.

Wind turbine blades are made from a composite of materials including glass reinforced plastic (fiberglass), wood and metal.

They cannot be recycled.

Why do the designers not use a different material that can be recycled?

• Carbon steel is too heavy

• The cost of using aluminum is too expensive

• There is no need to recycle the blades as the wind turbines are producing green energy

• There are no other suitable recyclable materials available at the moment
