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

11. An adhesive is a substance that is applied between two surfaces in order to bond them together






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 resistance a material offers to penetration or scratching






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






15. 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






16. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






17. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






18. The ability of a material to resist the propagation of cracks.






19. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






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






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






22. 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






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






24. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






25. 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






26. 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






27. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






28. The ability to analyse information in order to select an answer from alternatives






29. Two or more atoms that are normally bonded together covalently






30. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






31. 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.






32. A volume production process involving machines controlled by computers






33. The reduction of weight and ise of materials






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






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






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






37. A solution to a problem in one field is used to provide a new idea for a design problem in another






38. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






39. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






40. Designing in relation to materials during processing






41. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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






43. An anatomical 3D model of the human body






44. The difference in electrical potential between two points.

46. Obtaining users' responses.






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






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






49. 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






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