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 wide acceptance (and sale) of a product






2. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






3. Obtaining users' responses.






4. 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






5. This is the factor in which the machines multiplies the force put into it






6. The ability to link graphic screens together in such a way as to simulate motion or process






7. A 3D representation of an object drawn with the horizontal plane at 30






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






9. Water that contains animal - human or food waste and would not be reused for other purposes






10. Someone who immediately welcomes a technological change.






11. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






12. X and Y axes for cutting e.g. CNC Lathe






13. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






14. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






15. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






16. The most efficient way of designing and producing a product from the manufacturer's point of view






17. 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-

18. 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.






19. 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.






20. Designing in relation to materials during processing






21. The smallest part of an element that can exist chemically






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






23. A schematic representation of a process






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






25. 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






26. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






27. A group of products having common classification criteria. Members normally have many common parts and assemblies.






28. 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.






29. A computer program that attempts to simulate an abstract model of a particular system






30. The ability of a material to resist the propagation of cracks.






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






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






33. An emerging technology that interfaces the user via the sense of touch






34. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






35. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






36. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






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






38. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






39. The research and analysis of the mechanics of living organisms






40. 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






41. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






42. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






43. 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.






44. 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






45. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






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






47. The completeness and accuracy of a data set that is being used to inform a design decision
