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






2. A series of flat views of an object showing it exactly as it is in shape and size






3. Hypersensitivity to dietary substances






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






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






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






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






8. The most negative voltage the operational amplifier can output






9. 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






10. Pleasure derived from people's mental and emotional reactions to a product.






11. 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.






12. The mass per unit volume of a material






13. A volume production process involving machines controlled by computers






14. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






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






16. 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.






17. 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






18. 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






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






20. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






21. 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






22. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






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






24. Designers design specifically for optimum use of existing manufacturing capability






25. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






26. 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.






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






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






29. The exterior surface of a building's construction: the walls - windows - roof and floor. also referred to as 'building shell'






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






31. That proportion of a population with a dimension at or less than a given value






32. The reliance on the knowledge and skills of an expert in the operation of the product






33. 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






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






35. The use of computers to aid manufacturing






36. Natural compounds formed through geological processes






37. The ability to link graphic screens together in such a way as to simulate motion or process






38. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






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






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






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






42. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






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






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






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






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






47. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






48. 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






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






50. The resistance of an elastic body to deflection by an applied force.
