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






2. A volume production process involving machines controlled by computers






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. 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






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






6. 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






7. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






8. 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






9. A sugar (a carbohydrate) composed of two monosaccharide molecules






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






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






12. 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






13. The mass per unit volume of a material






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






15. A small- scale production process centred on manual skill






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






17. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






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






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






20. The reliance on the knowledge and skills of an expert in the operation of the product






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






22. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






23. The feed speed is the rate at which the cutting tools moves in x - y and z paths






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






25. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






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






27. 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-

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






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






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






31. The number of bits per second produced by a digital system






32. Two or more atoms that are normally bonded together covalently






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






34. 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






35. The use of the suns energy to heat up water and air directly






36. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






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






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






39. An anatomical 3D model of the human body






40. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






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






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






43. Mechanical efficiency is the effectiveness of a simple machine






44. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






45. 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.






46. 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.






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






48. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






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






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