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






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






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






4. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






5. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






6. An adhesive is a substance that is applied between two surfaces in order to bond them together






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






8. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






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






10. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






11. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






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






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






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






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






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






17. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






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






19. 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.






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






21. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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






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






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






25. Tool path cuts straight X and Y paths






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






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






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






29. The research and analysis of the mechanics of living organisms






30. 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.






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






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






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






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






35. A computer program that attempts to simulate an abstract model of a particular system






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






37. The most negative voltage the operational amplifier can output






38. Pleasure derived from people's mental and emotional reactions to a product.






39. An adverse food- induced reaction that does not involve the immune system






40. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






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






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






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






44. Designers design specifically for optimum use of existing manufacturing capability






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






46. 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.






47. This is the factor in which the machines multiplies the force put into it






48. 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
