Year 11 November Mocks Flashcards
What is a co operative?
A type of business that is owned and run by its members.
What is a biodegradable material?
a material that can naturally break down into the soil.
What is duplex board and what is it used for?
when only one surface is seen. food packaging
What is foam core board and what is it used for?
making models and mounting posters
What is foil lined board and what is it used for?
package food
what is solid white board and what is it used for?
packaging individual items (primary packaging)
what is an input. Give an example
an external signal. pressing a switch
How can you identify a hardwood and give three examples?
they’re deciduous, tight grain, denser, slow growing.
oak, beech, ash
How can you identify a softwood and give three examples?
evergreen, fast-growing, needle like leaves, cones.
pine, larch, spruce
What does the word woven mean?
interlacing two sets of yarn
If you weave fibres does it make the product stronger? Explain.
yes because of the interlocking yarns, it makes it hardwearing.
How is kevlar made?
crude oil distilled, polymers melted, forced through tiny holes, cooled, long filaments
name three properties of manufactured board.
consistent board thickness, layered structure, resistant to warping. cheap, made from waste products
What is Just In Time Production? Explain.
a form of lean manufacturing, materials are delivered when needed and used as soon as they’re delivered. This reduces waste and resources used.
How can JIT be used to improve efficiency?
reduces waste like unnecessary use of time. Reduces need for storage.
Explain the process of soldering
relatively low temperature process
involves melting solder onto components
soldering iron is used
solder should be volcano shaped
Give three examples of ways to remove waste materials
recycle- melt plastic and remould
tessellating- arranging shapes so that many can be cut from a sheet
calculate SA - see how much material is needed
why is quality control used in manufacturing?
controls consistency and to make sure they meet manufacturing specification
What are the quality control methods associated with prototyping?
prototypes are a one off- If a prototype works well then the product might be manufactured in greater volumes. They help evaluate the manufacturing process and design.
What is the origin/ source of metal based materials?
rocks or ore
What is the origin/ source of paper and boards?
cellulose fibers
What is the origin/ source of polymers?
oil
What is the origin/ source of textile based materials?
fibers
What is the origin/ source of timber based materials?
trees
what is the process of timber based materials?
felling/ debarking/ conversion/ sawing/ seasoning
what is the process of paper and boards?
trees cut/ debarking/ cut into small pieces/ pulping/ washing/ bleaching/ pressed
what is the process for polymers?
crude oil extracted/ refined/ fractionally distilled/ polymerization or cracking/ used or moulded
Describe the process of pulping
-it converts wood into individual cellulose fibres
-mechanical pulping involves grinding down the wood
chemical pulping involves heating the wood with chemicals
- this dissolves other parts of the wood leaving fibres behind
what are the six R’s?
RePair ReUse ReCycle ReThink ReDuce ReFuse
what are product miles?
total miles a product travels from finishing manufacturing to its final retail destination
what is a carbon footprint? Example
total amount of CO2 which are emitted over the full life cycle of a product. planes
how can you make a product inclusive?
braille on packaging.
what does anthropometric mean?
human body measurement data
Why is anthropometric useful?
to make products the correct size
what is a manufacturing tolerance?
a range of measurements that a product has to be within
Give an example of collaboration and why is it important?
user involvement. get feedback on design ideas
Give three examples of classroom PPE
goggles
long hair tied back
aprons
Give two safety precautions for preparing to cut
don’t change parts when connected to mains
always secure work safely
Give two safety precautions for cutting
never use tools unless you’ve been taught how to
take necklaces off
Give two safety precautions for storage after
carry and store sharp tools safely
never leave tools unattended when they’re on
What does functional mean?
designed to be practical rather than attractive
what is a surface finish. Give 2 examples
added to a product after production to improve functionality or aesthetics. yacht varnish tanalising
What are the benefits of 3D drawings over 2D drawings?
you can see perspectives and it’s easier to get dimensions across
Explain what orthographic projection is.
They show a 3D object as a set of 2D drawings viewed from different angles
It is an accurate working drawing
What are prototypes?
full sized, fully functioning products or systems
they allow you to test the product and production methods
What ways can designers’ model and test prototype products?
they can give it to other people for feedback.
Prototypes are evaluated by checking that they meet the criteria of the design specification.
