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 specific manufacturing term - sometimes relating to one material group only






2. The use of the suns energy to heat up water and air directly






3. 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






4. Automated machines that require data to be inputted manually by a trained operator






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






6. The range of users for a particular product or system.






7. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






8. 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






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






10. 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






11. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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






13. The permanent deformation of a solid subjected to stress






14. 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






15. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






16. 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






17. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






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






19. Obtaining users' responses.






20. A series of flat views of an object showing it exactly as it is in shape and size






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






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






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






24. 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






25. An emerging technology that interfaces the user via the sense of touch






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






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






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






29. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






30. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






31. 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






32. 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.






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

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






36. To combine multiple signals for transmission over a single line or medium






37. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






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






39. The rate of flow of electrons






40. The most negative voltage the operational amplifier can output






41. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






42. A volume production process involving machines controlled by humans






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






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






45. 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






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