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






2. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






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






4. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






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






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






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






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






9. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






10. A schematic representation of a process






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






12. Hypersensitivity to dietary substances






13. The ability of a material to be drawn or extruded into a wire or other extended shapes






14. This is a measure of a material's ability to conduct electricity. a material with low electrical resistivity will conduct electricity well.






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






16. The permanent deformation of a solid subjected to stress






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






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






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






20. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.






21. 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

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






24. A volume production process involving machines controlled by computers






25. 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






26. The wide acceptance (and sale) of a product






27. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat
