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.

2. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






3. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






4. 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






5. 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






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






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






8. 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






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






10. A 3D representation of an object drawn with the horizontal plane at 30






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






12. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






13. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






14. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






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






17. 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






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






19. 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






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






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






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






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






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






25. 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






26. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






27. Natural compounds formed through geological processes






28. 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






29. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






30. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






31. 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.






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






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






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






35. 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






36. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






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






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






39. The most negative voltage the operational amplifier can output






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






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






42. The number of bits per second produced by a digital system






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






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