Engineering Metals and Properties Multiple Choice

A material is .............................. if it can withstand wear and tear over a long period of time - such as a concrete building exposed to the weather.

• Tough

• Durable

• Strong

• Hard

A material that can withstand a sudden impact without cracking, such as hammers made from iron with an ash handle has what as it's main property?

• Toughness

• Durability

• Strength

• Hardness

What is the category of properties that strength, toughness and elasticity fall under?

• Aesthetic

• Chemical

• Mechanical

• Thermal

.............................. strength is a squashing force. It is often used when calculating how much weight something can bear; such as the concrete foundations of a bridge.

• Compressive

• Shear

• Torsional

• Tensile

A pure, non-ferrous metal which can be drawn out (pulled) to create wires. It is often used to connect the internet to houses through wiring buried under the ground.

• Copper

• Iron

• Aluminium

• Brass

A material is described as .......................... when it can be stretched and spring back when let go. An example of this is a plane's wing. This is made of aluminium and can bend and flex in the wind without snapping.

• Plastic

• Elastic

• Malleable

• Strong

A cutting force; when a material has two forces acting on it in opposite directions. For example, tin snips use this movement when cutting through sheet metal.

• Shear

• Tensile

• Torsional

• Compression

The name for iron, or metals containing iron - they rust when exposed to water and oxygen.

• Ferrous Metals

• Non-Ferrous Metals

Compressive, shear, torsional, and tensional are all examples of this category of mechanical property.

• Strength

• Toughness

• Durable

• Hardness

What happens when a ferrous metal is exposed to air and water?

• It rusts

• It breaks

• It melts

• It molds
