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. Resources that are naturally replenished in a short time.






2. The ability to analyse information in order to select an answer from alternatives






3. Fabric with technology enhanced performance used in smart clothing - for example - enhanced stain resistance - breathability or incorporating input sensors






4. The smallest part of an element that can exist chemically






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






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






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






8. A broad way of categorizing the kinds of market the company is aiming for






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






10. 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






11. The creation of new - modified or updated products aimed mainly at a company's existing customers.






12. All aspects of the processing - preparation - storage - cooking - and serving of food to make sure that it is safe to eat






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






14. Coordination - based code that also includes feed speed and stop/start






15. 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.






16. Someone who immediately welcomes a technological change.






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






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






19. Flexible designs that can be adapted to changing technical and market requirements.






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






21. 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

22. Designing in a way that takes account of the environmental impact of the product throughout its life






23. A technique that uses a fluid support structure that can be washed and drained away. Used for more intricate internal construction where it would be difficult to break away supports.






24. A series of flat views of an object showing it exactly as it is in shape and size






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






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






27. Designing to enable the product to be manufactured using a specific manufacturing process - for example - injection moulding






28. The use of computers to aid the design process






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






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






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






32. 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






33. 3D printing process using a vat of photosensitive resin and a vertically moving platform. Laser beam directed onto surface of resin to print patter of current model's layer by hardening resin. Platform then moves down by a layer thickness so the next






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






35. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






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






37. 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






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






39. Low levels of food intake - which can be transitory (as a result of crisis) - seasonal or chronic (when it occurs on a continuing basis)






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






41. 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






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






43. 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-
