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 volume production process involving machines controlled by humans






2. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order

6. Involves a company both in the development of new products and in selling those products to new companies






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






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






9. 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






10. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






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






12. 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






13. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






14. 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.






15. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






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






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






18. The most negative voltage the operational amplifier can output






19. 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

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






25. 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






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






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






28. 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.






29. The ability of a material to withstand pulling forces.






30. The manufacture of 3D parts by removing (cutting) unwanted material from a block






31. 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






32. 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






33. 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






34. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






35. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






36. 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






37. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






38. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase

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






43. Someone who immediately welcomes a technological change.






44. A schematic representation of a process






45. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl
