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. Resources that are naturally replenished in a short time.






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






3. A small- scale production process centred on manual skill






4. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids

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






13. The use of computers to aid manufacturing






14. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






15. The resistance a material offers to penetration or scratching






16. The permanent deformation of a solid subjected to stress






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






18. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






19. 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






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






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






22. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






23. A volume production process involving machines controlled by computers






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






25. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






26. Finding new applications for different products - thereby opening up new markets






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






28. Automated machines that require data to be inputted manually by a trained operator






29. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






30. An isometric drawing of an object with more than one component that depicts how the parts of assemblies fit together






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






32. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






33. Mechanical efficiency is the effectiveness of a simple machine






34. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






35. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl

36. 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.






37. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






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






39. 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






40. A sequence of instructions to describe a set of actions






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






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






43. Using creative ability to produce a wide range of possible solutions to a problem

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






46. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






47. Obtaining users' responses.






48. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






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






50. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or
