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 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






2. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






3. 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)






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






5. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






6. 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






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






8. 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






9. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






10. A volume production process involving machines controlled by humans






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






12. A computer program that attempts to simulate an abstract model of a particular system






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






14. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






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






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






17. This is the factor in which the machines multiplies the force put into it






18. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






19. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






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






22. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






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






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






25. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






26. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






27. 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.






28. Computer simulation of a variety of mechanical and biological aspects of the human body






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






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






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






32. A volume production process involving machines controlled by computers






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






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






35. Someone who resists all technological change.






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






37. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






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






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






40. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






41. An emerging technology that interfaces the user via the sense of touch






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






43. The use of computers to aid the design process






44. 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






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






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






47. The rate of flow of electrons






48. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






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






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