15 of 61
Define the thermal properties of textiles
clothing is used as a thermal insulation, which is the reduction of heat transfer between the body and air. this works by trapping a layer of hot air close to the body to provide warmth
16 of 61
Explain how this property is used in the design and manufacture of products

Conductivity is the measure of how well a material allows an electrical currentt o pass through. metals are good conductors due to free electrons which are able to move freely which causes more collisions, passing on the electrical charge
18 of 61
Explain how this property is used in the design and manufacture of products
Copper is used in the manufacture of wires dues to its ability to conduct electricity. it has the highest electrical conductivity rating of all non precious metals making it the most suitable for the product.

What is Durability?
A materials ability or product to last a long time
27 of 61
What does Morphological analysis mean?
Developed by Fritz Zwicky for exploring all the possible solutions to a multi-dimensional, non-quantified computer problem. the system allows for reduction by identifying the possible solutions that actually exist within a seemingly complex design
28 of 61
What is Lateral Thinking?
This is a way of solving problems by using reasoning that is not immediately obvious
29 of 61
What is Disassembly/ Attribute Analysis?
When existing products are taken apart and reviewed in order to see flaws/ how it works or to compare to the product in design stages
30 of 61
What is Structural Technology?
This is the technology of putting parts and materials together to create supports, containers, shelters e
