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. 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.






2. 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






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






4. 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






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






6. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






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






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






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






10. The use of computers to aid manufacturing






11. 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






12. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






13. The use of computers to aid the design process






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






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






16. 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






17. 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






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






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






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






21. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






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






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






24. A schematic representation of a process






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






26. A broad way of categorizing the kinds of market the company is aiming for






27. Mechanical efficiency is the effectiveness of a simple machine






28. The resistance a material offers to penetration or scratching






29. 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






30. Food becoming unfit for consumption - for example - due to chemical or biological contamination






31. 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






32. Obtaining users' responses.






33. Natural compounds formed through geological processes






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






35. A 3D representation of an object drawn with the horizontal plane at 30






36. 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






37. A volume production process involving machines controlled by computers






38. X and Y axes for cutting e.g. CNC Lathe






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






40. Flexible designs that can be adapted to changing technical and market requirements.






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






42. The reduction of weight and ise of materials






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






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






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






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






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






48. Someone who resists all technological change.






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






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