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. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






2. The initial impetus for the development of a new product is generated from a demand from the market






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






4. To combine multiple signals for transmission over a single line or medium






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






6. 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






7. This is a measure of a material's ability to conduct electricity. a material with low electrical resistivity will conduct electricity well.






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






9. Where the impetus for a new design emanates from a technological development.






10. 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.






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






12. Clear representations of the final part. They provide a complete set of data for the product to be realized.






13. Someone who immediately welcomes a technological change.






14. A style or trend






15. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






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






17. The rate of flow of electrons






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






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






20. A short length of extruded pipe for use in blow moulding






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






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






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






24. 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






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






26. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt






27. The number of bits per second produced by a digital system






28. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






29. An adverse food- induced reaction that does not involve the immune system






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






31. Designing in relation to materials during processing






32. The reliance on the knowledge and skills of an expert in the operation of the product






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






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






35. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






36. The research and analysis of the mechanics of living organisms






37. A mixture composed of two or more substances with one substance acting as the matrix or glue






38. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






39. 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






40. A technique that uses break- away supports. Break- away structure can be difficult to remove from detailed areas.






41. The creation of new - modified or updated products aimed mainly at a company's existing customers.






42. Someone who resists all technological change.






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






44. 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.






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






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






47. 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






48. Natural compounds formed through geological processes






49. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






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