Year 7 DT Flashcards
What is a protractor used for?
Measuring angles
What is a compass used for in DT?
Drawing arcs or circles
What would you use a set square for?
Set squares can be used to draw perpendicular lines, angles, and complete shapes, such as squares, rectangles, and triangles
In the earliest stages of designing, sketches help you to visualise and record ideas for yourself. What are these called?
Thumbnails
What kind of drawing would you make to persuade the client your design is worth producing?
A presentation drawing
Which drawing must communicate the exact details of the design?
A working drawing
An_____________view is a way of showing three dimensions on a drawing.
Isometric
What type of paper is helpful when drawing isometric views?
Grid
Attaching samples of the materials used to drawing adds detail. What are these samples known as?
Swatches
What sort of drawing gives the impression of length, width and height?
Perspective drawing
In DT what word refers to the way a product looks and feels?
Aesthetics
Perspective drawings include_____________ point.
Vanishing
Accurate, detailed models that show exactly what the final design will look like are called……
Prototypes
What information does a design brief give you in DT?
A design brief is the statement a client gives to a designer outlining what they want their product to be like, eg ‘Design a drinks bottle holder for use while riding a bicycle’. The designer could also produce a brief on behalf of the client, as the client might have a problem but not know how to proceed
What is typography measured in?
The height of type is measured in points, and the width of a letter or a line of type is measured in picas.
How big or small something is using measurements is called what? These can be in millimetres, centimetres, inches or metres
Size/Dimensions
The way a product works, what it does is its __________
Function
What a product is made out of e.g. wood, metal or plastic
Materials
The making of a product by hand or machine is known as?
Manufacture
Types of plastic that can be reheated and reshaped over and over again making them recyclable
Thermoplastic polymers
Types of plastic that can only be heated and shaped once making them not recyclable
Thermosetting polymers
The study of how humans use objects and then making them comfortable for this use e.g. curved water bottles making them comfortable to hold
Ergonomics
The measurement of the size, proportions, and range of motion of the human body so a product can be made the right size.
Anthropometrics
Thread-like materials from plants which can be made into fabric
Natural Fibres
Artificial fibres made from synthetic polymers which come from oil, coal and other petrol based chemicals which can be made into fabric
Synthetic fibres
A material that is woven or knitted, such as cloth
Fabric
Plastics made using plant or animal material (cellulose or starch) and are biodegradable
Bioplastics
The wood from broad-leaved, mostly deciduous trees. They take longer to grow making them more expensive. E.g. Oak
Hardwood
The wood from conifers or evergreen trees with pine needles. They grow quicker than hardwood trees making them cheaper. E.g. Pine
Softwood
Made by converting logs into a variety of forms and gluing them together to create flat sheet materials. They tend to be stronger and much cheaper than hardwoods and softwoods.
Manufactured Boards eg Plywood, MDF, Chipboard, Hardboard and Veneer
Describing what is good or bad about an existing product to give designers inspiration and as well as a chance to learn from past design mistakes
Product Analysis
A list of conditions that a product should meet
Design specification
A written statement outlining the problem or design challenge including criteria and constraints.
Design Brief
Metals containing iron, they can rust and are magnetic
Ferrous metals
Metals that do not contain iron, they do not rust and are not magnetic
Non ferrous metals
Materials which change in response to their surroundings, such as light levels or temperature. E.g. thermochromic material changes colour when it gets hot
Smart materials
Made from trees and can come in various thicknesses known as GSM. Used for writing, drawing, packaging etc.
Papers and Boards
Using a computer to create a design rather than pencil and paper. E.g. 2D design or photoshop
CAD (Computer Aided Design)
Using computers to make a product rather than hand or power tools. E.g. laser cutters or 3D printers
CAM (Computer Aided Manufacturing)
Meeting the needs of the present without compromising the ability of future generations to meet their own needs. Being environmentally friendly and saving the planet.
Sustainable
Inquiring, developing ideas, creating a solution, evaluating are stages in what?
Design cycle
The process of identifying a simple problem or question and creating a solution.
Design problem
What is an orthographic drawing?
An orthographic drawing, also known as an orthographic projection, is a drawing in which a three dimensional object is represented in two dimensions. This is is done making multiple two dimensional drawings of the object, viewed from different angles. 2-D, top, front, side, used for blueprints and plans
