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






2. The most efficient way of designing and producing a product from the manufacturer's point of view






3. Designing in a way that takes account of the environmental impact of the product throughout its life






4. 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






5. 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






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






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






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






9. 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






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






11. 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






12. An anatomical 3D model of the human body






13. 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






14. Mechanical efficiency is the effectiveness of a simple machine






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






16. A group of products having common classification criteria. Members normally have many common parts and assemblies.






17. The smallest part of an element that can exist chemically






18. The cost required to maintain or repair a product or system.






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






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






21. 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






22. A volume production process involving machines controlled by computers






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






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






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






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






27. 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-

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






29. 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






30. Tool path is determined by individual Z coordinates across the product






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






32. Natural compounds formed through geological processes






33. A style or trend






34. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






35. 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






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






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






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






39. An emerging technology that interfaces the user via the sense of touch






40. Involved in development systems to ensure that products or services are designed and produced to meet or exceed customer requirements and expectations.






41. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






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






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






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






45. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt






46. A test of the performance of some new product under the conditions in which it will be used






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






48. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






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






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