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.

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






13. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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

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






21. 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






22. Pleasure derived from people's mental and emotional reactions to a product.






23. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






24. 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






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






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






27. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress

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






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






31. 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

37. Reuse of a product in the same context or in a different context.






38. 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-
