Core Technical Principles Flashcards
when did the industrial revolution begin?
1760
what is CAD?
computer aided design - using computers and software to design products
what is CAT?
computer aided testing - using computers and software to test the functionality of products before they are made.
What is CAM?
Computer Aided Manufacturing - using automated machines to manufacture products eg. computer numerical control (CNC) machines, laser cutters and 3D printers.
What is enterprise?
When an idea is turned into a business proposal which is viable as a commercial product
What is a patent?
A legal process which shows that you are the first person to register an idea or invention and that other people can’t copy it
What is a cooperative?
An enterprise which is owned by members who are a part of its workforce or customers.
What are LunaTik Multi-Touch Watch Kits?
A product made in 2010 by Scott Wilson to turn old ipod nanos into touch watches. He needed to raise $15,000 on kickstarter.com to start production, but he raised almost $1,000,000 in one month.
Give the appearance, 3 characteristics and 3 uses of PLA

Give the appearance, 3 characteristics and 3 uses of PHB
Appearance - smooth or textured finish
characteristics - stable, stiff, quite brittle, non-toxic, easily processed and moulded, limited chemical resistance, fully biodegradable
uses - bottles, pots, household items, disposable food containers
What is flexible MDF?
MDF which has had grooves cut, leaving about 2mm of surface MDF, making it flexible but still retain its surface finish.
What are the uses of flexible MDF?
Modern wave-shaped or curved furniture and interior walls
What metal is most commonly used for artificial joints or other orthopaedic applications or dental implants and why?
Titanium because it does not react with the human body, is very strong and light and has excellent corrosion resistance
What are optical fibres?
They are wires which carry a signal faster than copper wires and don’t suffer from electromagnetic interference like copper wires do by transmitting light along the class core.
Give 3 uses for fibre optics
passing information quickly over the internet, endoscopes (small cameras used to investigate areas inside the body without the need for invasive surgery), novelty lighting displays
What are 3 characteristics of graphene?
very conductive, flexible, stretchable, incredibly strong, lightweight, impermeable, very thin
Give 3 possible uses of graphene
Medical industry, electronic industry, energy industry
What does LCD stand for?
Liquid Crystal Display
What are the two types of LCD screen?
Monochrome and full colour
How are pixels on an LCD screen made visible?
Applying a voltage to them
Give 3 characteristics of LCD screens
Low power consumption, sharp image, compact, colour screens can be very bright, bad contrast, restricted viewing angle
Give 3 uses of LCD screens
small or low power electronic devices, watches, clocks, microwaves, satellite navigation systems, in-car entertainment, flat computer and TV screens
What are nanomaterials?
materials most commonly between 1 and 100 nm, but can be up to 1000 nm
Give 3 uses for nanomaterials
Miniaturisation and improved conductivity in electronics, protective coatings in textiles, anti-bacterial agent, UV protection
