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. 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.






2. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.






3. The width of the electromagnetic spectrum that a signal occupies






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






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






6. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






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






8. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.






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






10. 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






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






12. A volume production process involving machines controlled by computers






13. 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






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






15. The rate of flow of electrons






16. The use of the suns energy to heat up water and air directly






17. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






18. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






19. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






20. Automated machines that require data to be inputted manually by a trained operator






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






22. Resources that are naturally replenished in a short time.






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. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






25. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






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






27. An adhesive is a substance that is applied between two surfaces in order to bond them together






28. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






29. The opposition that a substance offers to the flow of electric current.






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






31. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






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






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






34. The use of computers to aid manufacturing






35. 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






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

38. A device that is able to laser cut and engrave 2D shapes






39. Clear representations of the final part. They provide a complete set of data for the product to be realized.






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






41. 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

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






45. The manufacture of 3D parts by depositing molten material in a series of layers






46. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker
