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. Natural compounds formed through geological processes






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






3. Increasing sales to existing customers or finding new customers for an existing product






4. Automated machines that require data to be inputted manually by a trained operator






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






6. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






7. 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






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






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






10. Involves a company both in the development of new products and in selling those products to new companies






11. A measurement of the relative percentages of fat and muscle mass in the human body - in which weight in kilograms is divided by height in metres and the result used as and index of obesity






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






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






14. The width of the electromagnetic spectrum that a signal occupies






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






16. 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






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






18. 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






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






20. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






21. 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






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






23. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






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






25. The observation of people using a product and collection of comments from people who have used a product.






26. The initial impetus for the development of a new product is generated from a demand from the market






27. Mechanical efficiency is the effectiveness of a simple machine






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






29. An anatomical 3D model of the human body






30. 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






31. The ability of a material to be drawn or extruded into a wire or other extended shapes






32. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






33. 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






34. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






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






36. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






37. The use of computers to aid the design process






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






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






40. A computer program that attempts to simulate an abstract model of a particular system






41. 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






42. The wide acceptance (and sale) of a product






43. 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-

48. Tool path cuts straight X and Y paths






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






50. 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.
