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






2. Computer simulation of a variety of mechanical and biological aspects of the human body






3. Tool path is circular - which is useful for round and curved objects






4. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






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






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






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






8. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






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






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






11. A schematic representation of a process






12. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl


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






14. 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






15. Someone who immediately welcomes a technological change.






16. 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)






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






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






19. A test of the performance of some new product under the conditions in which it will be used






20. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






21. 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






22. A style or trend






23. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






24. The resistance a material offers to penetration or scratching






25. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






26. The passive solar practice of placing windows - or other transparent media - and reflective surfaces so that - during the day - natural sunlight procivides effective internal illumination






27. X and Y axes for cutting e.g. CNC Lathe
