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.

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






3. 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






4. Increased body weight in relation to height - when compared to some standard of acceptable or desirable weight. a body mass index of more than 25 is defined as overweight by the World Health Organization. overweight may or may not be due to increase






5. A device that is used to cut 2D shapes from card and vinyl






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






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






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

10. The observation of people using a product and collection of comments from people who have used a product.






11. Water that contains animal - human or food waste and would not be reused for other purposes






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






13. 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






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






15. Automated machines that require data to be inputted manually by a trained operator






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






17. The angle of taper - expressed in degrees (usually 5






18. 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






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






20. In chemistry - an amino acid is any molecule that contains both amino and carboxylic acid functional groups. in biochemistry - this is shorter and more general term is frequently used to refer to alpha amino acids in which the amino and carboxylate f






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






22. Someone who immediately welcomes a technological change.






23. Pleasures derived from satisfying peoples taste - values and aspirations






24. Designers design specifically for optimum use of existing manufacturing capability






25. 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






26. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






27. 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






28. Tool path cuts straight X and Y paths






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






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






31. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






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






33. The rate of flow of electrons






34. A model using mathematical symbols that can be manipulated numerically






35. The permanent deformation of a solid subjected to stress






36. 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






37. 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






38. 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

47. The number of bits per second produced by a digital system






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






49. 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-
