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






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






3. 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-

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






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






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






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






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






9. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






10. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






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






12. The research and analysis of the mechanics of living organisms






13. Involving the use of sense organs






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






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






16. 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






17. 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.






18. Tool path cuts straight X and Y paths






19. The use of computers to aid the design process






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






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






22. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






23. The reduction of weight and ise of materials






24. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






25. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






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






27. Computer simulation of a variety of mechanical and biological aspects of the human body






28. 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






29. 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






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






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






32. 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






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






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






35. Someone who immediately welcomes a technological change.






36. 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






37. 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






38. This is a measure of a material's ability to conduct electricity. a material with low electrical resistivity will conduct electricity well.






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






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






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






42. 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






43. 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.






44. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






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






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






47. 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.
