Flexible structures ~ Tents
Modern tents use light weight fabrics which are given structure with equally light weight poles and guy lines.
The picture shown here of a small very light weight tent is made from gortex nylon material which is breathable, water and wind proof even when it has been screwed up in a bag or rucksack.
The hooped flexible poles at each end are fed through ‘tubes’ in the fabric which then hold the tend open, the guy lines hold the poles in the in place and help to keep the structure rigid.
The poles in this tent are in TENSION, the guy lines and fabric are also in TENSION. This is what helps keep this tent errect and waterproof.

The real exam 2008
Ok you done the paper but was it waht you expected? Were the questions fair? Did the questions make sense?
Question 4: Serving Spoons:
Serving Spoon A: these are made from Beech (hardwood). They have been made from this is because it is a close grained hardwood which is easy to work with and does not require any surface finish. Beech is commonly used for food/kitchen items because it is non toxic and safe.
Serving Spoon B: Injection Moulded Plastic; probably HIPS or acrylic. Reason for choice, ridgid, hygienic and safe for food use.
Serving Spoon C: stainless steel. Stainless steel is often used for food/catering equipment because it is durable, easy to keep clean and easiy to make into robust objects.
