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






2. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






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






4. Coordination - based code that also includes feed speed and stop/start






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






6. 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.






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






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






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






10. Natural compounds formed through geological processes






11. The spontaneous representation of ideas on paper without the use of technical aids






12. Someone who resists all technological change.






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






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






15. 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)






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






17. 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






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






19. The angle of taper - expressed in degrees (usually 5






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






21. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






22. Waste water generated from processes such as washing dishes - bathing and laundry






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






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

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






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






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






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






30. 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






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






32. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






33. 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






34. The technique of heating and cooling a building naturally without the use of mechanical equipment






35. Costs that vary with output - for example - fuel or raw materials.






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






37. 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.






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






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. Mechanical efficiency is the effectiveness of a simple machine






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

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






49. 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






50. 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
