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






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






3. The formation of a gel by using gelatin or by the heat treatment of starch and water to break open starch granules - for example custard






4. Water that contains animal - human or food waste and would not be reused for other purposes






5. Waste water generated from processes such as washing dishes - bathing and laundry






6. 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.






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






8. The use of computers to aid the design process






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






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






11. Someone who needs some convincing before embracing technological change.






12. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






13. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






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






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






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






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






19. A device that is able to laser cut and engrave 2D shapes






20. Involving the use of sense organs






21. Costs that vary with output - for example - fuel or raw materials.






22. A filamentous material long in relation to its width/breadth






23. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






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






25. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






26. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






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






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






29. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






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






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






32. The ability to analyse information in order to select an answer from alternatives






33. 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.






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






35. The assessment of the effect a product has on the environment from the initial concept to disposal






36. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






37. 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

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






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






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






41. A sugar (a carbohydrate) composed of two monosaccharide molecules






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






43. 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






44. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






45. A style or trend






46. 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
