Subjects : engineering, ib
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 difference in electrical potential between two points.






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






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






4. 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.






5. A volume production process involving machines controlled by computers






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






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






8. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






9. The reduction of weight and ise of materials






10. 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)






11. Someone who resists all technological change.






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






13. A schematic representation of a process






14. 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






15. An emerging technology that interfaces the user via the sense of touch






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






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






18. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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






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






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






22. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






23. 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






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






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






26. 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






27. A mixture composed of two or more substances with one substance acting as the matrix or glue






28. 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






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






30. The number of bits per second produced by a digital system






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






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






33. A style or trend






34. Tool path cuts straight X and Y paths






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






36. 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






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






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






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






40. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






41. The resistance a material offers to penetration or scratching






42. 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






43. 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






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






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






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






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






48. 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-
