IB Design Technology Vocab

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. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






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






3. 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






4. The mass per unit volume of a material






5. A sequence of instructions to describe a set of actions






6. A broad way of categorizing the kinds of market the company is aiming for






7. The difference in electrical potential between two points.






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






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






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






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






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






13. Two or more atoms that are normally bonded together covalently






14. 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






15. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






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






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






18. 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.






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






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






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






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






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






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






25. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






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






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






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






29. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






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






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






32. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






33. 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.






34. 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






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






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






37. The rate of flow of electrons






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






39. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






40. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






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






42. This is the factor in which the machines multiplies the force put into it






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






44. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






45. The most efficient way of designing and producing a product from the manufacturer's point of view






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






47. 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






48. 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.






49. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl
