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 mixture composed of two or more substances with one substance acting as the matrix or glue






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






3. Using creative ability to produce a wide range of possible solutions to a problem






4. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






5. Limited volume production (a set number of items to be produced)






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






7. A compound that cannot be made in the body but has to be provided ready- made in the diet - for example - vitamins - essential fatty acids - and essential amino acids






8. 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






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






10. Hypersensitivity to dietary substances






11. A volume production process involving machines controlled by humans






12. 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






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






14. Involving the use of sense organs






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






16. The simplest form of carbohydrate - consisting of one sugar residue. they are the building blocks for disaccharides and polysaccharides






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






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






20. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






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






22. 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






23. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier






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






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






26. Tool path cuts straight X and Y paths






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






28. 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






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






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






31. 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.






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






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






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






35. Obtaining users' responses.






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






37. The creation of new - modified or updated products aimed mainly at a company's existing customers.






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






39. A volume production process involving machines controlled by computers






40. Mechanical efficiency is the effectiveness of a simple machine






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






42. Analysing a situation that would benefit from redesign - and working out a strategy for improving it






43. Designing in relation to materials during processing






44. A series of flat views of an object showing it exactly as it is in shape and size






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






46. The transfer of an idea from one context to another






47. The rate of flow of electrons






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






49. 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
