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. Mechanical efficiency is the effectiveness of a simple machine






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






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






4. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-

5. 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






6. The ability of a material to resist the propagation of cracks.






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






8. 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






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






10. A situation where the firm does not allocate space to the storage of components or completed items - but instead orders them (or manufactures them) when required. large storage areas are not needed and items that are not ordered are not made






11. Clear representations of the final part. They provide a complete set of data for the product to be realized.






12. An individual working outside or inside an organisation who is committed to the invention of a novel product and often becomes isolated because he or she is engrossed with ideas that imply change and are resisted by others






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






14. 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)






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






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






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






18. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






19. 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






20. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances






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






22. A designer creates a part geometry independent of the assembly or any other component. although there are often some design criteria established before modelling the part - this information is not shared between models. once all part models are compl

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






24. A style or trend






25. Involving the use of sense organs






26. Fatty acids are carboxylic acids with a long hydrocarbon chain - usually straight






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






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






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






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






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






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






33. The application of methods and systems found in nature to the study and design of engineering systems and modern technology






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






35. Small changes to the design of a product that seem trivial but the cumulative effect of which over a longer period can be very significant






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






37. A sugar (a carbohydrate) composed of two monosaccharide molecules






38. Excessively high amount of body fat in relation to lean body mass. a body mass index of more than 30 is defined as obese by the World Health Organization






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






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






41. A plant or animal in which the DNA has been altered through the insertion of genetic material from another source. genetic modification is the most often used in agricultural crops to increase the resistance to herbicides or to engineer pesticides in






42. The way a person or group lives - including patterns of social relations - consumption - entertainment and dress






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






44. A device that is able to laser cut and engrave 2D shapes






45. A sophisticated CIM system that manufactured products to individual customer orders. the benefits of economy of scale are gained whether the order is for a single item or thousands






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






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






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