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 formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






2. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






3. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






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






5. Increasing sales to existing customers or finding new customers for an existing product






6. A computer- based machine or robot that has the ability to learn from information gained through feedback






7. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






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






9. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






10. The feed speed is the rate at which the cutting tools moves in x - y and z paths






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






12. 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

14. Flexible designs that can be adapted to changing technical and market requirements.






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






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

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






19. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






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

22. Involves a company both in the development of new products and in selling those products to new companies






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






24. Someone who immediately welcomes a technological change.






25. The reduction of weight and ise of materials






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