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 volume production process involving machines controlled by computers






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






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






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






5. A volume production process involving machines controlled by humans






6. Mechanical efficiency is the effectiveness of a simple machine






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. Tool path cuts straight X and Y paths






9. 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






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






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






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






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






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






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






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






17. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






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. 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






20. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






21. The number of bits per second produced by a digital system






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






23. Involving the use of sense organs






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






25. An anatomical 3D model of the human body






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






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






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






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






30. 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






31. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






32. 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.






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






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






35. 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






36. Designing in relation to materials during processing






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






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






39. Natural compounds formed through geological processes






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






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






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






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






44. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






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






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






47. 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.






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






49. 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






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