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. An anatomical 3D model of the human body






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






3. The technique of heating and cooling a building naturally without the use of mechanical equipment






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






6. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






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






8. Using creative ability to produce a wide range of possible solutions to a problem






9. A broad way of categorizing the kinds of market the company is aiming for






10. A device that is used to cut 2D shapes from card and vinyl






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






12. Someone who immediately welcomes a technological change.






13. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






14. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






15. The most negative voltage the operational amplifier can output






16. A style or trend






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






18. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.






19. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






20. 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






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






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






23. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






24. 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






25. 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-

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






27. 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






28. 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






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






30. The transfer of an idea from one context to another






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






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






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






34. 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






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






36. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






37. 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






38. 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






39. 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
