Walk Around
Task 1
Plywood is a composite material. Plywood is created by gluing together sheets of wood together. This bonding method used is permanent, given that plywood is not intended to separate into its various components.
Task 2
This sink in the 500 building has a ceramic bowl. Ceramics have the property of wear and oxidation resistance.
Oxidation can start when contact with water is made, which is why it's important that the sink bowl must resist oxidation.
The bowl makes constant contact with water and must be wear resistant.
Task 3
Non-Ferrous : copper
conducts electricity the best and is the most flexible, making it ideal for wires
Ferrous: iron
less flexible and conductive than non-ferrous but has more tensile strength, making it ideal to be used in forks
Alloy: steel
the most tensile strength and makes it ideal for scissors so it is easy to cut objects
Task 4
softwood cabinets
softwood is cheaper and has a 10 year growth cycle compared to hard woods 50 year. softwood is also less dense and thus lighter, meaning these cabinets are easier to install
hardwood piano keys
hardwood is more dense giving a more tactile feel when pressing on the keys. They also have more tensile strength due to their density, making them last longer over a long time of use
Task 5
soda glass
This commercial glass and is the most commonly used. Has medium to low thermal shock, in other words, it will shatter going from cold to hot or the other way. Window panes, glassware, drink bottles, etc
borosilicate (pyrex)
The chemical composition of Soda Glass is altered by the addition of oxides which improve thermal conductivity. Cookware, science equipment such as beakers.
Laminated
It is layers of glass and plastic sheets between them. When impacted the glass fragments are held in place. This prevents cracks from growing Bulletproof glass, windscreens, bank teller windows,
toughened glass
This makes the outside is in compression and the slower cool interior is in tension. When it is impacted it shatters into little pieces rather than sharp shards. Side windows of cars, shower glass or design contexts where there is a potential for impact.
