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 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.






2. A volume production process involving machines controlled by humans






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






4. Obtaining users' responses.






5. An anatomical 3D model of the human body






6. 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






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






8. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






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






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






11. An adverse food- induced reaction that does not involve the immune system






12. 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






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






14. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






15. The difference in electrical potential between two points.






16. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






17. The quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons and is measured in coulombs






18. The creation of new - modified or updated products aimed mainly at a company's existing customers.






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






20. Where the impetus for a new design emanates from a technological development.






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






22. The most negative voltage the operational amplifier can output






23. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






24. The manufacture of 3D parts by depositing molten material in a series of layers






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






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






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






28. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






29. A specific manufacturing term - sometimes relating to one material group only






30. Flexible designs that can be adapted to changing technical and market requirements.






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






32. The use of computers to aid manufacturing






33. A solution to a problem in one field is used to provide a new idea for a design problem in another






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






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






36. 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.






37. Food becoming unfit for consumption - for example - due to chemical or biological contamination






38. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






39. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain
