November Test Flashcards
Two engineering materials commonly supplied in sheet form
Aluminium
Copper
This is a composite material
Glass Reinforced Plastic
This is a ceramic
Porcelain
2 benefits of sheet materials
Limits waste
Cheap
What’s the idler gear?
Gear in the middle that doesn’t do much
How is new technology used when researching engineering products
We can see how a product will perform before we have made it
How is new technology used to communicate when designing engineering products?
Cloud to work on same file
Email and video-calling
Two benefits of using robotics when making an engineered product?
Precise and identical
Quicker than humans
Three disadvantages of using robots to make an engineered product?
If a robot is doing something wrong it doesn’t know so just keeps on doing it
Maintenance breaks mean stopping the production line
Expensive
Define composite materials
A composite material is when 2 or more materials with different properties are bonded together to make a material with properties different from the component materials.
Define an alloy
Materials made from different examples of the same material types, e.g. Metal alloys
What’s a compliant material?
Basic, easy to form material. E.g. Paper
Give some examples of composite materials
Kevlar, MDF
Give some examples of alloys
Brass, bronze, Stainless steel
Describe forming
Shaped in a cold state
