IB Design Technology Vocab

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






2. Fatty acids that are required in the human diet. this means that it cannot be synthesized by the body from other fatty acids and must be obtained from food.






3. Morphologic synthesis is an elaboration of attribute listing. after completing the list of attributes - list them along two sides of a 2D grid. think creatively about how the attributes can be developed through new ideas in each of the cells to impro






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






5. 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

6. An anatomical 3D model of the human body






7. Designing a product so that when it becomes obsolete it can easily and economically be taken apart - the components reused or repaired - and the materials recycled






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






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






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






12. 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






13. A realistic picture of the final model - offering some machining data - but containing no data about the interior of the part.






14. 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






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






16. X and Y axes for cutting e.g. CNC Lathe






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






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






19. The use of computers to aid manufacturing






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






21. CO2 laser is used to sinter a thin layer of heat- fusible powder that gradually builds up the 3D model.






22. 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






23. Hypersensitivity to dietary substances






24. 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






25. Rebuilding a product so that it is in an 'as new' condition - and is generally used in the context of car engines and tyres.






26. A solution to a problem in one field is used to provide a new idea for a design problem in another






27. The property of being biologically compatible by not producing a toxic - injurious or immunological response in living tissue






28. 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






29. Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.






30. 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






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






32. 3 linear axes (X -Y -Z) and two rotary axes (A -B) e.g. milling machine






33. The transfer of an idea from one context to another






34. Limited volume production (a set number of items to be produced)






35. The direct introduction to molten plastic under pressure into a die - which then cools rapidly - allowing the formed object to be released from the mould






36. The relationship between what something - for example - a product - is worth and the cash amount spent on it.






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






38. The rate of flow of electrons
