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






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






3. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






4. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






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






6. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






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






9. Mechanical efficiency is the effectiveness of a simple machine






10. 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






11. A schematic representation of a process






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






13. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






14. The most negative voltage the operational amplifier can output






15. 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.






16. 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.






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






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






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. 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






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






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






23. Someone who immediately welcomes a technological change.






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






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






26. Tool path is circular - which is useful for round and curved objects






27. Someone who resists all technological change.






28. 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






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






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






31. 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






32. A small- scale production process centred on manual skill






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






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






35. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-


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






37. The initial impetus for the development of a new product is generated from a demand from the market






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






39. Increasing sales to existing customers or finding new customers for an existing product






40. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






41. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






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






43. A mixture composed of two or more substances with one substance acting as the matrix or glue
