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. 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.






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






3. Reuse of a product in the same context or in a different context.






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






5. The range of users for a particular product or system.






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






7. The most negative voltage the operational amplifier can output






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






9. 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.






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






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






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






13. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






14. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






15. Involving the use of sense organs






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






17. A series of flat views of an object showing it exactly as it is in shape and size






18. An anatomical 3D model of the human body






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






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






21. A style or trend






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






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






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






25. 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






26. 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






27. 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






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






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






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






31. 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






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






33. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






34. 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

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






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






37. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase

43. The resistance a material offers to penetration or scratching






44. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






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