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. 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






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






3. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






4. The use of computers to aid manufacturing






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






6. The permanent deformation of a solid subjected to stress






7. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






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






9. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






10. 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






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






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






13. The reconstruction or renewal of any part of an existing structure or device.






14. 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






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






16. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






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






18. 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






19. The spontaneous representation of ideas on paper without the use of technical aids






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






21. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






22. 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






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






24. The resistance a material offers to penetration or scratching






25. Natural compounds formed through geological processes






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






27. A schematic representation of a process






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






29. 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-


30. Clear representations of the final part. They provide a complete set of data for the product to be realized.






31. 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






32. The assessment of the effect a product has on the environment from the initial concept to disposal






33. 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.






34. Obtaining users' responses.






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






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






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






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






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






41. 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






42. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






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






44. The cost required to maintain or repair a product or system.






45. 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


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






47. Hypersensitivity to dietary substances






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