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. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






2. A system of manufacturing that uses computers to integrate the processing of production - business and manufacturing in order to create more efficient production lines






3. 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






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






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






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






7. The spontaneous representation of ideas on paper without the use of technical aids






8. A volume production process involving machines controlled by computers






9. 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






10. 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






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






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






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






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






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






16. The reduction of weight and ise of materials






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






18. 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






19. Finding new applications for different products - thereby opening up new markets






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






21. A functional prototype - or a functional appearance model - is a prototype that 'looks like' and 'works like' a production product. although they are made from prototype materials - these models simulate actual finishes and colours as well as mechani






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






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






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






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






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






27. 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






28. To combine multiple signals for transmission over a single line or medium






29. Someone who needs some convincing before embracing technological change.






30. A computer program that attempts to simulate an abstract model of a particular system






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






32. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.






33. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






34. A sequence of instructions to describe a set of actions






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






36. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






37. Mechanical efficiency is the effectiveness of a simple machine






38. The ability of a material to be drawn or extruded into a wire or other extended shapes






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






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






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






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






43. 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
