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






2. The difference in electrical potential between two points.






3. To combine multiple signals for transmission over a single line or medium






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






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






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






7. Designing in relation to materials during processing






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






9. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






10. The assessment of the effect a product has on the environment from the initial concept to disposal






11. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






12. 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.






13. 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






14. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






15. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






16. The permanent deformation of a solid subjected to stress






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






18. Natural compounds formed through geological processes






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






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






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






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






23. 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






24. The completeness and accuracy of a data set that is being used to inform a design decision






25. 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






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






27. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






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






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






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






31. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






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






33. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






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






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






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






37. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






38. 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






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






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






41. A volume production process involving machines controlled by computers






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






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






44. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.






45. 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.






46. 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






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