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.

15. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






16. 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

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






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






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






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






24. 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.






25. The technique of heating and cooling a building naturally without the use of mechanical equipment
