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. The ability to analyse information in order to select an answer from alternatives






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






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






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






6. The reduction of weight and ise of materials






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






8. 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






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






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






11. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






12. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






13. The ability of a material to resist the propagation of cracks.






14. A volume production process involving machines controlled by computers






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






16. This is the factor in which the machines multiplies the force put into it






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






18. 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






19. 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






20. 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






21. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






22. Limited volume production (a set number of items to be produced)






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






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






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






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






27. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






28. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






29. 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






30. 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.






31. 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-

32. The permanent deformation of a solid subjected to stress






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






34. The smallest part of an element that can exist chemically






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






36. 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

37. The manufacture of 3D parts by depositing molten material in a series of layers






38. An individual (often craft- produced) article or a prototype for a larger- scale production






39. Small changes to the design of a product that seem trivial but the cumulative effect of which over a longer period can be very significant






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






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






42. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






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






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






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






46. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






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






48. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






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