1. Look at the following three chairs.

Name the material used to manufacture each chair.

Why are they suitable? Refer to physical and mechanical properties in relation to function and manufacture.

How has each chair been manufactured?

HARD WOOD - OAK or any suitable hardwood.

1b. Why is it a suitable material?
Refer to physical and mechanical properties in relation to function and manufacture.

This is a suitable material because it is strong and has the ability to stand up to forces being applied without it bending, breaking, shattering or deforming in any way. It is a durable material and hard wearing and will stand up to years of use. It has the property of elasticity being able to flex and spring back to its original position, a property a material for a chair requires.

Oak is an attractive wood with a visually attractive grain and colour. It can be finished effectively with varnishes.
A natural wood of this type can be sourced from sustainable forests whereby materials collected are replaced by replanting.

1c. How has each chair been manufactured?

The chair has been manufactured as either one-off or batch production. Mortise and tenon joints are the most suitable as these provide the strength required by a piece of furniture of this type. Joints such as plain mortise and tenon, wedged mortise and tenon, dowelled mortise and tenon are all suitable and provide an effective permanent joint. A suitable glue such as PVA or cascamite can be used to permanently join the parts together.
