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.

24. Costs that vary with output - for example - fuel or raw materials.






25. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






26. A model using mathematical symbols that can be manipulated numerically






27. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






28. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes
