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 use of computers to aid the design process






2. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






3. Designing in relation to materials during processing






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






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






6. 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.






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






8. 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






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






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






11. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






12. 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






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






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






15. 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






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






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






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






19. Someone who resists all technological change.






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






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






22. 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






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






24. 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






25. Tool path cuts straight X and Y paths






26. Someone who immediately welcomes a technological change.






27. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






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






29. The most negative voltage the operational amplifier can output






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






31. Natural compounds formed through geological processes






32. The opposition that a substance offers to the flow of electric current.






33. 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






34. The rate of flow of electrons






35. Using creative ability to produce a wide range of possible solutions to a problem






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






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






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