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






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






4. The initial impetus for the development of a new product is generated from a demand from the market






5. The mass per unit volume of a material






6. The technique of heating and cooling a building naturally without the use of mechanical equipment






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






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






9. The rate of flow of electrons






10. The permanent deformation of a solid subjected to stress






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






12. The width of the electromagnetic spectrum that a signal occupies






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






14. The opposition that a substance offers to the flow of electric current.






15. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






16. Waste water generated from processes such as washing dishes - bathing and laundry






17. 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






18. 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






19. 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






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






21. The reconstruction or renewal of any part of an existing structure or device.






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






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






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






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






26. Involving the use of sense organs






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






28. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






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






30. A style or trend






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






32. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.

34. Resources that are naturally replenished in a short time.






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






36. 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






37. 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.






38. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






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