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 reduction of weight and ise of materials






2. 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






3. Designing in relation to materials during processing






4. The angle of taper - expressed in degrees (usually 5






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






6. The mass per unit volume of a material






7. 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.






8. The rate of flow of electrons






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






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






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






12. 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






13. 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.






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






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






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






17. An anatomical 3D model of the human body






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






19. 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.






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






21. A device that is used to cut 2D shapes from card and vinyl






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






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






24. Hypersensitivity to dietary substances






25. A schematic representation of a process






26. 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






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






28. 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






29. That proportion of a population with a dimension at or less than a given value






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






31. Someone who resists all technological change.






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






33. The resistance of an elastic body to deflection by an applied force.






34. 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






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






36. The ability of a material to resist the propagation of cracks.






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






38. The opposition that a substance offers to the flow of electric current.






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






40. 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.
