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. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






2. 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






3. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






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






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






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






7. 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






8. 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






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






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






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






12. 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.






13. 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






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






15. 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






16. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






17. The use of computers to aid the design process






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






19. X and Y axes for cutting e.g. CNC Lathe






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






21. 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)






22. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






23. The difference in electrical potential between two points.






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






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






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






27. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






28. 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






29. The completeness and accuracy of a data set that is being used to inform a design decision






30. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






31. Designing in a way that takes account of the environmental impact of the product throughout its life






32. The mass per unit volume of a material






33. A volume production process involving machines controlled by computers






34. 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






35. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






36. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-
