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. A small- scale production process centred on manual skill






2. Hypersensitivity to dietary substances






3. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






4. 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






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






6. 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






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






8. Involving the use of sense organs






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






10. 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






11. 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






12. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






13. A solution to a problem in one field is used to provide a new idea for a design problem in another






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






15. 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






16. Costs that vary with output - for example - fuel or raw materials.






17. 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






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






19. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






20. The mass per unit volume of a material






21. A technique that uses break- away supports. Break- away structure can be difficult to remove from detailed areas.






22. The reduction of weight and ise of materials






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






24. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






25. A volume production process involving machines controlled by humans






26. The rate of flow of electrons






27. Natural compounds formed through geological processes






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






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






30. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






31. The permanent deformation of a solid subjected to stress






32. 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.






33. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






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






35. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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






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






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






39. The assessment of the effect a product has on the environment from the initial concept to disposal






40. Limited volume production (a set number of items to be produced)






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






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






43. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






44. A short length of extruded pipe for use in blow moulding






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






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






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






48. The psychological condition resulting from inadequacy or imbalance in food intake or from poor absorption of food consumed






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






50. A style or trend
