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. 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.






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






3. 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.






4. 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.






5. 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






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






7. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






8. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






9. The reduction of weight and ise of materials






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






11. The mass per unit volume of a material






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






13. 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






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






15. The use of consumer reports and newspaper items to follow historical development. useful sources of information could include CD-Roms - such as encyclopedias and newspapers - or more specific discs - subject specific magazines - and manufacturers' in






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






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






18. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






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






20. Using the materials from obsolete products to create other products.






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






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






23. The observation of people using a product and collection of comments from people who have used a product.






24. Natural compounds formed through geological processes






25. The psychological condition resulting from inadequacy or imbalance in food intake or from poor absorption of food consumed






26. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.






27. 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






28. Hypersensitivity to dietary substances






29. 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






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






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






32. A volume production process involving machines controlled by humans






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






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






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






36. Designing in relation to materials during processing






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






38. 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-
