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






2. 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






3. 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.






4. The observation of people using a product and collection of comments from people who have used a product.






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






6. 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-

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






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






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






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






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






17. 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






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






19. 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






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






21. 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.






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






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






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






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






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






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






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






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






30. The most negative voltage the operational amplifier can output






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






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






33. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






34. The reduction of weight and ise of materials






35. Computer simulation of a variety of mechanical and biological aspects of the human body






36. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






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






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






39. A schematic representation of a process






40. 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






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






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






43. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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