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. Using the materials from obsolete products to create other products.






2. The angle of taper - expressed in degrees (usually 5






3. 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

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






5. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






6. The cost required to maintain or repair a product or system.






7. 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






8. 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






9. 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






10. The difference in electrical potential between two points.






11. The mass per unit volume of a material






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






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






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






15. 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






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






17. 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






18. A model using mathematical symbols that can be manipulated numerically






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






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






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






22. A volume production process involving machines controlled by computers






23. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






24. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






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






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






27. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






28. This is the factor in which the machines multiplies the force put into it






29. 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






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






31. A style or trend






32. Natural compounds formed through geological processes






33. 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.






34. The use of computers to aid manufacturing






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






36. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






37. 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






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






39. Obtaining users' responses.






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






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






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






43. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






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






45. The ability to analyse information in order to select an answer from alternatives






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






47. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






48. 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.






49. 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






50. 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
