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. Food becoming unfit for consumption - for example - due to chemical or biological contamination






2. 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






3. The mass per unit volume of a material






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






5. X -Y -Z plus additional rotary motion e.g. Lathe with milling head






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






7. 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.






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






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






11. An influential individual - usually working within an organization - who develops an enthusiasm for a particular idea or invention and 'champions' it within that organization.






12. The use of computers to aid the design process






13. A form of group think. a group with a recommended size of 10-12 people first devises wild ideas - all of which are written down. no criticism or evaluation is allowed until this is finished - as it is impossible to be creative and critical at the sam






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






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






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






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






18. 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






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






20. The rate of flow of electrons






21. Refers to materials and devices that operate at the nanoscale. 'Nano' means a billionth. A nanometer is one- billionth of a meter






22. A type of fastening that is not supposed to be removed. it is only possible to remove such joins by drilling - cutting or grinding the join away






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






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






25. Someone who resists all technological change.






26. The use of the suns energy to heat up water and air directly






27. An adhesive is a substance that is applied between two surfaces in order to bond them together






28. 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






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






30. The initial impetus for the development of a new product is generated from a demand from the market






31. 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






32. A schematic representation of a process






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






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






35. A filamentous material long in relation to its width/breadth






36. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage






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






38. The width of the electromagnetic spectrum that a signal occupies






39. 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
