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. Where the impetus for a new design emanates from a technological development.






2. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






3. 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.






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






5. A model using mathematical symbols that can be manipulated numerically






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






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






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






9. 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






10. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






11. A schematic representation of a process






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






13. Involving the use of sense organs






14. Hypersensitivity to dietary substances






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






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






17. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-

18. X and Y axes for cutting e.g. CNC Lathe






19. 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






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






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






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






23. The resistance a material offers to penetration or scratching






24. Coordination - based code that also includes feed speed and stop/start






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






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






27. 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






28. Tool path cuts straight X and Y paths






29. 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






30. The resistance of an elastic body to deflection by an applied force.






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






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






33. A sugar (a carbohydrate) composed of two monosaccharide molecules






34. The quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons and is measured in coulombs






35. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat






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






37. A filamentous material long in relation to its width/breadth






38. The initial impetus for the development of a new product is generated from a demand from the market






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






40. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.
