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






2. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






3. 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






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






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






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






7. 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






8. The reconstruction or renewal of any part of an existing structure or device.






9. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






10. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl

11. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






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






13. 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






14. 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






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






16. Water that contains animal - human or food waste and would not be reused for other purposes






17. Involving the use of sense organs






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






19. The observation of people using a product and collection of comments from people who have used a product.






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






21. 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






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






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






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






25. The resistance of an elastic body to deflection by an applied force.






26. A volume production process involving machines controlled by humans






27. The most negative voltage the operational amplifier can output






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






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






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






31. 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






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






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






34. Obtaining users' responses.






35. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






36. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






37. 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






38. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






39. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics
