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






2. 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-

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






4. The most negative voltage the operational amplifier can output






5. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






6. A schematic representation of a process






7. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






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






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. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






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






12. 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






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






14. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






15. The reconstruction or renewal of any part of an existing structure or device.






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






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






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






19. Someone who needs some convincing before embracing technological change.






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






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






22. Finding new applications for different products - thereby opening up new markets






23. The ability of a material to be drawn or extruded into a wire or other extended shapes






24. The business of putting an invention in a market place and making it a success






25. 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






26. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






27. 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






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






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






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






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






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






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






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






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






36. The ability of a material to withstand pulling forces.






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






38. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






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






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.






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






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






43. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






44. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






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






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






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






48. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






49. The transfer of an idea from one context to another






50. The ability to simulate a real situation on the screen and interact with it in a near- natural way.
