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






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






3. The most negative voltage the operational amplifier can output






4. 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






5. A schematic representation of a process






6. Clear representations of the final part. They provide a complete set of data for the product to be realized.






7. 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






8. The spontaneous representation of ideas on paper without the use of technical aids






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






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






11. 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.






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






13. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






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






15. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






16. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






17. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






18. 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






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






20. 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






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






22. Using creative ability to produce a wide range of possible solutions to a problem






23. Involves a company both in the development of new products and in selling those products to new companies






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






25. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






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






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






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






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






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






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






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






33. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






34. 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






35. 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






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






37. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






38. A test of the performance of some new product under the conditions in which it will be used






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






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






41. 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






42. Mechanical efficiency is the effectiveness of a simple machine






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






44. A volume production process involving machines controlled by computers






45. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






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