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. 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






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






3. The width of the electromagnetic spectrum that a signal occupies






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






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






6. The manufacture of 3D parts by depositing molten material in a series of layers






7. 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






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






9. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.






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






11. 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.






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






13. 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






14. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






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






16. 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






17. The use of computers to aid manufacturing






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






19. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






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






21. 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






22. Tool path is determined by individual Z coordinates across the product






23. The ability of a material to withstand pulling forces.






24. Someone who resists all technological change.






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






26. Increasing sales to existing customers or finding new customers for an existing product






27. 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






28. A style or trend






29. 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






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






31. Involving the use of sense organs






32. The research and analysis of the mechanics of living organisms






33. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






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






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






36. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






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






38. A series of flat views of an object showing it exactly as it is in shape and size






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






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






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






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






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






44. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






45. A sugar (a carbohydrate) composed of two monosaccharide molecules






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






47. A 3D representation of an object drawn with the horizontal plane at 30






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






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






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