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






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






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






4. An emerging technology that interfaces the user via the sense of touch






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






6. 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






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






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






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






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






11. 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






12. Flexible designs that can be adapted to changing technical and market requirements.






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






14. 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






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






16. 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






17. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






18. The use of computers to aid manufacturing






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






20. The use of the suns energy to heat up water and air directly






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






22. Obtaining users' responses.






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






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






25. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






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






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






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






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






30. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






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






32. A style or trend






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






34. The reliance on the knowledge and skills of an expert in the operation of the product






35. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






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






37. 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






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






39. Involving the use of sense organs






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






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






42. 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






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