AQA GCSE Engineering: Engineering design and communication overview quiz quiz

The brief is a detailed measurable list of requirements; the specification is a short statement of the overall problem

They mean exactly the same thing and both list every measurable requirement

The brief is a short statement of the problem; the specification is a detailed measurable list of requirements

The brief is the drawn pictorial view; the specification is the written manufacturing plan

Because it is finished in a single pass with no changes once the brief is written down

Because it must always be carried out by a large multi-disciplinary engineering team

Because it relies entirely on computers and never on testing physical prototypes

Because you loop back to improve a solution as evaluation reveals weaknesses

Third-angle orthographic projection

A single isometric pictorial projection

A vanishing-point perspective drawing

An exploded assembly view

The exact single size of the part with no variation whatsoever allowed during manufacture

The surface finish and colour applied to the completed part after machining

The material and heat treatment the part is made from before assembly

The allowed variation in a dimension so the part can be made and inspected

Computer-aided manufacture; it uses computer-controlled machines to make the part

Computer-aided modelling; it only stores and displays finished 3D models on screen

Computer-aided measurement; it inspects finished parts against the drawing tolerances

Computer-assisted marketing; it advertises the finished product to potential customers

It needs no skilled operators or expensive training before it can be used

Models can be tested and viewed from any angle before anything is made

It is always completely free to set up with no software or hardware cost

It removes the need for any written specification or measurable requirements

Mass-produce the final finished product cheaply for large retail markets

Replace the written design specification with a quick physical sample

Quickly build a physical model to test fit and function

Avoid the need to make any engineering drawings at all

Recycle, reverse, restart

Reduce, replace, return

Reuse, remove, restock

Reduce, reuse, recycle

They raise output and quality but remove some jobs while creating new higher-skilled ones

They only ever create brand new jobs and never once reduce the overall size of the workforce

They only ever destroy jobs and always lower the quality of the finished products

They have no measurable effect at all on employment, output, cost or product quality

Only the purchase cost of the raw material used to make the part

The whole life from sourcing materials to disposal

Only how the finished product looks and feels to the customer

Only the energy used during the manufacturing stage of the product
