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 permanent deformation of a solid subjected to stress






2. The creation of new - modified or updated products aimed mainly at a company's existing customers.






3. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






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






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






6. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






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






8. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






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






10. 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






11. 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






12. 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






13. The ability of a material to be drawn or extruded into a wire or other extended shapes






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






15. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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






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. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






19. 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.






20. A model using mathematical symbols that can be manipulated numerically






21. 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






22. The smallest part of an element that can exist chemically






23. 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






24. The manufacture of 3D parts by removing (cutting) unwanted material from a block






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






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






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






28. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






29. Designing in relation to materials during processing






30. The ability of a material to withstand pulling forces.






31. 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






32. A filamentous material long in relation to its width/breadth
