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.
1. Finding new applications for different products - thereby opening up new markets






2. Limited volume production (a set number of items to be produced)






3. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






4. Clear representations of the final part. They provide a complete set of data for the product to be realized.






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






6. The use of the suns energy to heat up water and air directly






7. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






8. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






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






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






11. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






12. An individual (often craft- produced) article or a prototype for a larger- scale production






13. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






14. The completeness and accuracy of a data set that is being used to inform a design decision






15. 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






16. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






17. The most efficient way of designing and producing a product from the manufacturer's point of view






18. A group of products having common classification criteria. Members normally have many common parts and assemblies.






19. The opposition that a substance offers to the flow of electric current.






20. The use of computers to aid the design process






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






22. 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






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






24. The use of computers to aid manufacturing






25. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






26. The rate of flow of electrons






27. 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






28. Resources that are naturally replenished in a short time.






29. The manufacture of 3D parts by removing (cutting) unwanted material from a block






30. A mixture that contains at least one metal. this can be a mixture of metals or a mixture of metals and non - metals






31. The resistance a material offers to penetration or scratching






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






33. 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






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






35. Using the materials from obsolete products to create other products.






36. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






37. Obtaining users' responses.






38. Coordination - based code that also includes feed speed and stop/start






39. 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






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






41. A solution to a problem in one field is used to provide a new idea for a design problem in another






42. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






43. The ability to simulate a real situation on the screen and interact with it in a near- natural way.






44. 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
