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. Hypersensitivity to dietary substances






2. 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






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






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






5. A specific manufacturing term - sometimes relating to one material group only






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






7. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






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






9. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






10. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






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






12. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






13. Natural compounds formed through geological processes






14. 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.






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






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






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






18. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






19. The resistance a material offers to penetration or scratching






20. A series of flat views of an object showing it exactly as it is in shape and size






21. A schematic representation of a process






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






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






24. 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.






25. 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)






26. The rate of flow of electrons






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






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






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






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






31. 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






32. 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






33. 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.






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






35. The use of computers to aid the design process






36. Involves a company both in the development of new products and in selling those products to new companies






37. 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






38. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






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






40. A short length of extruded pipe for use in blow moulding






41. 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






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






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






44. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






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






46. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






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






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






49. 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






50. The completeness and accuracy of a data set that is being used to inform a design decision
