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






2. A schematic representation of a process






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






4. 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






5. 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.






6. Someone who immediately welcomes a technological change.






7. The mass per unit volume of a material






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






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






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






11. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt






12. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






13. Designers design specifically for optimum use of existing manufacturing capability






14. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






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






16. A solution to a problem in one field is used to provide a new idea for a design problem in another






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






18. Food becoming unfit for consumption - for example - due to chemical or biological contamination






19. Hypersensitivity to dietary substances






20. 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






21. A computer- based machine or robot that has the ability to learn from information gained through feedback






22. The completeness and accuracy of a data set that is being used to inform a design decision






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






24. The smallest part of an element that can exist chemically






25. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






26. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






27. Obtaining users' responses.






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






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






30. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






31. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






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






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






35. A device that is used to cut 2D shapes from card and vinyl






36. The reduction of weight and ise of materials






37. 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.






38. The rate of flow of electrons






39. That proportion of a population with a dimension at or less than a given value






40. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






41. 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






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






43. Water that contains animal - human or food waste and would not be reused for other purposes






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






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






46. The wide acceptance (and sale) of a product






47. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






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






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






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