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 recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






2. The difference in electrical potential between two points.






3. A small- scale production process centred on manual skill






4. 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






5. 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






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






7. The process of adding the information contained - for example - in the human voice to a suitable electromagnetic carrier






8. 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






9. 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






10. 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






11. 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






12. Obtaining users' responses.






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






14. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






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






16. 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-

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






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






22. 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

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






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






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






35. Costs that vary with output - for example - fuel or raw materials.
