Subjects : engineering, ib
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 permanent deformation of a solid subjected to stress






2. The rate of flow of electrons






3. The quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons and is measured in coulombs






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






5. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






6. 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






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






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






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






10. Pleasures derived from satisfying peoples taste - values and aspirations






11. 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)






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






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






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






15. 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






16. 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






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






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






19. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






20. Designers design specifically for optimum use of existing manufacturing capability






21. Clear representations of the final part. They provide a complete set of data for the product to be realized.






22. A solution to a problem in one field is used to provide a new idea for a design problem in another






23. 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






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






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






26. Someone who resists all technological change.






27. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt






28. Someone who immediately welcomes a technological change.






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






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






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






32. Involving the use of sense organs






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






34. 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






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






36. 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






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






38. A computer program that attempts to simulate an abstract model of a particular system






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






40. A volume production process involving machines controlled by computers






41. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






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






43. The ability of a material to withstand pulling forces.






44. A device that is used to cut 2D shapes from card and vinyl






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






46. Mechanical efficiency is the effectiveness of a simple machine






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






48. An adverse food- induced reaction that does not involve the immune system






49. Obtaining users' responses.






50. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam
