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






2. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






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






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






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






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






7. Natural compounds formed through geological processes






8. 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.






9. Someone who needs some convincing before embracing technological change.






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






11. To combine multiple signals for transmission over a single line or medium






12. 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






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






14. The transfer of an idea from one context to another






15. 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






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






17. An isometric drawing of an object with more than one component that depicts how the parts of assemblies fit together






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






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






20. 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

21. Pleasures derived from satisfying peoples taste - values and aspirations






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






23. A volume production process involving machines controlled by humans






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






25. 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






26. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat






27. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






28. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






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






30. 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






31. Where the impetus for a new design emanates from a technological development.






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






33. The completeness and accuracy of a data set that is being used to inform a design decision






34. Finding new applications for different products - thereby opening up new markets






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






36. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






37. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






38. Waste water generated from processes such as washing dishes - bathing and laundry






39. The reduction of weight and ise of materials






40. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






41. 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






42. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-

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






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






45. The resistance a material offers to penetration or scratching






46. The permanent deformation of a solid subjected to stress






47. The most negative voltage the operational amplifier can output






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






49. 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






50. 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.
