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 small- scale production process centred on manual skill






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






3. The smallest part of an element that can exist chemically






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






5. Waste water generated from processes such as washing dishes - bathing and laundry






6. Natural compounds formed through geological processes






7. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






8. Designing in relation to materials during processing






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






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






11. X and Y axes for cutting e.g. CNC Lathe






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






13. Hypersensitivity to dietary substances






14. The width of the electromagnetic spectrum that a signal occupies






15. Limited volume production (a set number of items to be produced)






16. A volume production process involving machines controlled by computers






17. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






18. Two or more atoms that are normally bonded together covalently






19. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






20. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






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






22. A sequence of instructions to describe a set of actions






23. 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






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






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






26. A schematic representation of a process






27. 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.






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






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






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






31. Designing in a way that takes account of the environmental impact of the product throughout its life






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






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






34. An anatomical 3D model of the human body






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






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






37. The ability to analyse information in order to select an answer from alternatives






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






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






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






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






42. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






43. A style or trend






44. 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






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






46. 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






47. 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






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






49. 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






50. The use of computers to aid the design process
