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. An adhesive is a substance that is applied between two surfaces in order to bond them together






2. That proportion of a population with a dimension at or less than a given value






3. The mass per unit volume of a material






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






5. 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






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






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






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. 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.






10. A model using mathematical symbols that can be manipulated numerically






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






12. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






13. 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

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






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






16. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






17. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






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 use of computers to aid the design process






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






21. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






22. Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.






23. 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






24. 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






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






26. 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-

27. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






28. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






29. A sequence of instructions to describe a set of actions






30. 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






31. 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






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






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






34. The use of consumer reports and newspaper items to follow historical development. useful sources of information could include CD-Roms - such as encyclopedias and newspapers - or more specific discs - subject specific magazines - and manufacturers' in






35. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






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






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






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






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






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






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






42. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






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






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






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