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






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






3. The difference in electrical potential between two points.






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






5. 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






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






7. Limited volume production (a set number of items to be produced)






8. A schematic representation of a process






9. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






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






11. 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






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






13. A technique that uses break- away supports. Break- away structure can be difficult to remove from detailed areas.






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






15. The assessment of the effect a product has on the environment from the initial concept to disposal






16. The feed speed is the rate at which the cutting tools moves in x - y and z paths






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






18. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






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






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






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






22. A specific manufacturing term - sometimes relating to one material group only






23. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






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






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






26. The rate of flow of electrons






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






28. The mass per unit volume of a material






29. Natural compounds formed through geological processes






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






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






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






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






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






35. 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)






36. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






37. Resources that are naturally replenished in a short time.






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






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






40. Someone who resists all technological change.






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






42. Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.






43. 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.






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






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






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