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 are carboxylic acids with a long hydrocarbon chain - usually straight






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






3. The most negative voltage the operational amplifier can output






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






5. 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.






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






7. Tool path cuts straight X and Y paths






8. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






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






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






11. 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)






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






13. 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






14. Mechanical efficiency is the effectiveness of a simple machine






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






16. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






17. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






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






19. Designing in relation to materials during processing






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






21. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






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






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






24. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






25. The permanent deformation of a solid subjected to stress






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






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






28. The resistance a material offers to penetration or scratching






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






30. The business of putting an invention in a market place and making it a success






31. Computer simulation of a variety of mechanical and biological aspects of the human body






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






33. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






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






35. 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






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






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






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






39. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






40. A small- scale production process centred on manual skill






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






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






43. Hypersensitivity to dietary substances






44. 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
