Subjects : engineering, ib
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. Hypersensitivity to dietary substances






2. The assessment of the effect a product has on the environment from the initial concept to disposal






3. Increasing sales to existing customers or finding new customers for an existing product






4. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






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






6. 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-

7. The manufacture of 3D parts by removing (cutting) unwanted material from a block






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






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






10. A situation where a company keeps a small stock of components (or complete items) or ones that take a long time to make - just in case of a rush order






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






12. The resistance of an elastic body to deflection by an applied force.






13. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






14. 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






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






16. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






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






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. Tool path cuts straight X and Y paths






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






21. 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






22. Representative users perform realistic tasks by interacting with a paper version of the user- product interface that is manipulated by a person acting as a computer - who does not explain how the interface works






23. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






24. 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






25. Reuse of a product in the same context or in a different context.






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






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






28. Natural compounds formed through geological processes






29. Obtaining users' responses.






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






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. 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






33. An adverse food- induced reaction that does not involve the immune system






34. 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
