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. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






3. Hypersensitivity to dietary substances






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






5. Natural compounds formed through geological processes






6. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






7. Mechanical efficiency is the effectiveness of a simple machine






8. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






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






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






11. The technique of heating and cooling a building naturally without the use of mechanical equipment






12. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






13. 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






14. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






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






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






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






18. A series of flat views of an object showing it exactly as it is in shape and size






19. A broad way of categorizing the kinds of market the company is aiming for






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






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






22. Coordination - based code that also includes feed speed and stop/start






23. 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






24. Tool path is circular - which is useful for round and curved objects






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






26. Using the materials from obsolete products to create other products.






27. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






28. A sugar (a carbohydrate) composed of two monosaccharide molecules






29. The ability of a material to resist the propagation of cracks.






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






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






32. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






33. A volume production process involving machines controlled by humans






34. 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






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






36. 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






37. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






38. 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.






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






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






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

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






46. The angle of taper - expressed in degrees (usually 5






47. 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






48. Someone who resists all technological change.






49. 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
