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. Mechanical efficiency is the effectiveness of a simple machine






2. 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






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






4. A schematic representation of a process






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






6. To combine multiple signals for transmission over a single line or medium






7. A volume production process involving machines controlled by humans






8. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






9. The ability to link graphic screens together in such a way as to simulate motion or process






10. 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






11. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






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






13. An emerging technology that interfaces the user via the sense of touch






14. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






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

22. The use of computers to aid manufacturing






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






24. Natural compounds formed through geological processes






25. Someone who resists all technological change.






26. 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
