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. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






2. 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






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






4. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat






5. The difference in electrical potential between two points.






6. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






7. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






8. The permanent deformation of a solid subjected to stress






9. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






10. Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.






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






12. The quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons and is measured in coulombs






13. 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






14. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






15. The angle of taper - expressed in degrees (usually 5






16. 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.






17. Designing in relation to materials during processing






18. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






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






20. Designing in a way that takes account of the environmental impact of the product throughout its life






21. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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






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






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






25. The smallest part of an element that can exist chemically






26. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






27. The transfer of an idea from one context to another






28. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






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






30. The reduction of weight and ise of materials






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






32. A mixture composed of two or more substances with one substance acting as the matrix or glue






33. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






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






35. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






36. Pleasure derived from the sensory organs - including pleasures connected with touch - taste - smell and sensual pleasure






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






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






39. This is the factor in which the machines multiplies the force put into it






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






41. The range of users for a particular product or system.






42. A short length of extruded pipe for use in blow moulding






43. 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






44. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.
