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. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






2. That proportion of a population with a dimension at or less than a given value






3. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






4. The manufacture of 3D parts by depositing molten material in a series of layers






5. The range of users for a particular product or system.






6. A schematic representation of a process






7. The reduction of weight and ise of materials






8. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






9. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.






10. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






11. Obtaining users' responses.






12. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






13. The rate of flow of electrons






14. Hypersensitivity to dietary substances






15. The assessment of the effect a product has on the environment from the initial concept to disposal






16. The quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons and is measured in coulombs






17. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






18. X and Y axes for cutting e.g. CNC Lathe






19. Water that contains animal - human or food waste and would not be reused for other purposes






20. The mass per unit volume of a material






21. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






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






23. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






24. Tool path is determined by individual Z coordinates across the product






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






26. 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






27. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






28. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






29. A broad way of categorizing the kinds of market the company is aiming for






30. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






31. A volume production process involving machines controlled by computers






32. Small changes to the design of a product that seem trivial but the cumulative effect of which over a longer period can be very significant






33. 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






34. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.






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






36. A sugar (a carbohydrate) composed of two monosaccharide molecules






37. The transfer of an idea from one context to another






38. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






39. The use of consumer reports and newspaper items to follow historical development. useful sources of information could include CD-Roms - such as encyclopedias and newspapers - or more specific discs - subject specific magazines - and manufacturers' in






40. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






41. Tool path is circular - which is useful for round and curved objects






42. The reconstruction or renewal of any part of an existing structure or device.






43. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






44. Pleasures derived from satisfying peoples taste - values and aspirations






45. The difference in electrical potential between two points.






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






47. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






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






49. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






50. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design
