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. Reuse of a product in the same context or in a different context.






2. 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






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






4. 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






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






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






7. A volume production process involving machines controlled by computers






8. The production of large amounts of standardized products on production lines - permitting very high rates of production per worker






9. Pleasures derived from satisfying peoples taste - values and aspirations






10. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






11. 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






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






13. 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






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






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






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






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






18. A specific manufacturing term - sometimes relating to one material group only






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






20. The biological value of a protein refers to how much of the nitrogen content of food is retained by the body. the biological value of proteins ranges from 50% to 100% and is a measure of how much dietary protein source can support growth






21. The research and analysis of the mechanics of living organisms






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






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






24. A computer- based machine or robot that has the ability to learn from information gained through feedback






25. The most negative voltage the operational amplifier can output






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






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






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






29. 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






30. Designing in relation to materials during processing






31. Excess material on a moulded part - forming a thin fan where two parts of the mould meet






32. 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






33. The use of computers to aid manufacturing






34. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






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






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






37. 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






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






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






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






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






42. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






43. 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






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






45. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






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






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






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






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






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