Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






2. The width of the electromagnetic spectrum that a signal occupies






3. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






4. The business of putting an invention in a market place and making it a success






5. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






6. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






7. Designers design specifically for optimum use of existing manufacturing capability






8. The wide acceptance (and sale) of a product






9. The cost required to maintain or repair a product or system.






10. Involving the use of sense organs






11. A specific manufacturing term - sometimes relating to one material group only






12. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






13. An individual (often craft- produced) article or a prototype for a larger- scale production






14. A series of flat views of an object showing it exactly as it is in shape and size






15. A 3D representation of an object drawn with the horizontal plane at 30






16. A filamentous material long in relation to its width/breadth






17. A test of the performance of some new product under the conditions in which it will be used






18. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






19. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






20. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






21. The spontaneous representation of ideas on paper without the use of technical aids






22. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






23. Resources that are naturally replenished in a short time.






24. A device that is used to cut 2D shapes from card and vinyl






25. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






26. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






27. The manufacture of 3D parts by removing (cutting) unwanted material from a block






28. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






29. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






30. The technique of heating and cooling a building naturally without the use of mechanical equipment






31. Costs that vary with output - for example - fuel or raw materials.






32. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






33. Limited volume production (a set number of items to be produced)






34. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






35. A device that is able to laser cut and engrave 2D shapes






36. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






37. A group of products having common classification criteria. Members normally have many common parts and assemblies.






38. The most efficient way of designing and producing a product from the manufacturer's point of view






39. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






40. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






41. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






42. Food becoming unfit for consumption - for example - due to chemical or biological contamination






43. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute

45. The smallest part of an element that can exist chemically






46. The ability to link graphic screens together in such a way as to simulate motion or process






47. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas
