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






2. 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






3. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






4. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






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






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






7. A style or trend






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






9. 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.






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






11. 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






12. 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






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






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






15. 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.






16. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






17. Increasing sales to existing customers or finding new customers for an existing product






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






19. An anatomical 3D model of the human body






20. Involving the use of sense organs






21. Someone who resists all technological change.






22. 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.






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






24. Natural compounds formed through geological processes






25. The permanent deformation of a solid subjected to stress






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






27. The resistance a material offers to penetration or scratching






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






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






30. 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.






31. The use of computers to aid manufacturing






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






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






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






35. 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






36. A short length of extruded pipe for use in blow moulding






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






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






39. A sugar (a carbohydrate) composed of two monosaccharide molecules






40. 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






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






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






43. Food becoming unfit for consumption - for example - due to chemical or biological contamination






44. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






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






46. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






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






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