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






2. The difference in electrical potential between two points.






3. The mass production of a product via a flow line based on the interchangeability of parts - pre- processing of materials - standardization and work division






4. Small changes to the design of a product that seem trivial but the cumulative effect of which over a longer period can be very significant






5. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






6. A volume production process involving machines controlled by humans






7. 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

13. The creation of new - modified or updated products aimed mainly at a company's existing customers.






14. Food becoming unfit for consumption - for example - due to chemical or biological contamination






15. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






16. Obtaining users' responses.






17. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner

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






22. A volume production process involving machines controlled by computers






23. 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

29. The psychological condition resulting from inadequacy or imbalance in food intake or from poor absorption of food consumed






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






31. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






32. An adhesive is a substance that is applied between two surfaces in order to bond them together






33. 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






34. A sequence of instructions to describe a set of actions






35. The feed speed is the rate at which the cutting tools moves in x - y and z paths






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






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






38. 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






39. Someone who immediately welcomes a technological change.






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






41. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-
