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 filamentous material long in relation to its width/breadth






2. The rate of flow of electrons






3. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






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






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






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






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






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






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






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






11. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






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






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






14. Hypersensitivity to dietary substances






15. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.






16. 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.






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






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






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






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






21. 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






22. Someone who resists all technological change.






23. The ability of a material to be drawn or extruded into a wire or other extended shapes






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






25. 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






26. A style or trend






27. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






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






29. The reliance on the knowledge and skills of an expert in the operation of the product






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






31. 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






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. 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






34. The most negative voltage the operational amplifier can output






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






36. The mass per unit volume of a material






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






38. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






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






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






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






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






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






44. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






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






46. The opposition that a substance offers to the flow of electric current.






47. 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






48. A group of products having common classification criteria. Members normally have many common parts and assemblies.






49. Tool path cuts straight X and Y paths






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