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. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






2. Computer simulation of a variety of mechanical and biological aspects of the human body






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






4. 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






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






6. An individual (often craft- produced) article or a prototype for a larger- scale production






7. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






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






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






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






11. A volume production process involving machines controlled by humans






12. 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






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






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






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






16. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






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






18. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






19. Obtaining users' responses.






20. 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






21. A group of products having common classification criteria. Members normally have many common parts and assemblies.






22. 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.






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






24. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






25. Involving the use of sense organs






26. 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






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






28. The reconstruction or renewal of any part of an existing structure or device.






29. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






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






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






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






33. A solution to a problem in one field is used to provide a new idea for a design problem in another






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






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






36. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






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






38. The permanent deformation of a solid subjected to stress






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






40. Resources that are naturally replenished in a short time.






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






42. The use of computers to aid the design process






43. 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.






44. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






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






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






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






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






50. 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.
