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






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






3. 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






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






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






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






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






8. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






9. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






10. 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.






11. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






12. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






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






14. Hypersensitivity to dietary substances






15. A schematic representation of a process






16. 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.






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






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






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






20. 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






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






22. 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






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






24. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






25. Pleasure derived from people's mental and emotional reactions to a product.






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






27. Flexible designs that can be adapted to changing technical and market requirements.






28. The mass per unit volume of a material






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






30. Coordination - based code that also includes feed speed and stop/start






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






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






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






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






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






36. 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






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






38. 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-

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






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






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






42. 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.






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






44. 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






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






46. The most negative voltage the operational amplifier can output






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






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






49. The research and analysis of the mechanics of living organisms






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