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






2. 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






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






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






5. The mass per unit volume of a material






6. 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






7. Finding new applications for different products - thereby opening up new markets






8. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






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






10. The use of computers to aid manufacturing






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






12. The initial impetus for the development of a new product is generated from a demand from the market






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






14. 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






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






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






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






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






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






20. 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.






21. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






22. 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






23. A schematic representation of a process






24. The range of users for a particular product or system.






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






26. 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






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






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






29. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






30. A test of the performance of some new product under the conditions in which it will be used






31. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






32. 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






33. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






34. The business of putting an invention in a market place and making it a success






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






36. Limited volume production (a set number of items to be produced)






37. 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






38. Someone who immediately welcomes a technological change.






39. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






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






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






42. Tool path is circular - which is useful for round and curved objects






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






44. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






45. 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






46. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






47. A computer- based machine or robot that has the ability to learn from information gained through feedback






48. 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.






49. A device that is able to laser cut and engrave 2D shapes






50. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl
