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






2. A volume production process involving machines controlled by humans






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






4. A technique that uses break- away supports. Break- away structure can be difficult to remove from detailed areas.






5. 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






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






7. The rate of flow of electrons






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






9. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






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






11. Involving the use of sense organs






12. The manufacture of 3D parts by depositing molten material in a series of layers






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






14. Tool path cuts straight X and Y paths






15. An adhesive is a substance that is applied between two surfaces in order to bond them together






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






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






18. This is a measure of a material's ability to conduct electricity. a material with low electrical resistivity will conduct electricity well.






19. 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

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






21. A comparative measure of poverty - literacy - education - life expectancy - childbirth and other factors for countries worldwide






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






23. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






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






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. 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






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






28. An isometric drawing of an object with more than one component that depicts how the parts of assemblies fit together






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






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






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






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






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






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






35. The use of computers to aid manufacturing






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






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






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






39. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






40. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






41. An anatomical 3D model of the human body






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






43. An adverse food- induced reaction that does not involve the immune system






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






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






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






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






48. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






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






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