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






2. The research and analysis of the mechanics of living organisms






3. Using creative ability to produce a wide range of possible solutions to a problem






4. A computer program that attempts to simulate an abstract model of a particular system






5. The manufacture of 3D parts by removing (cutting) unwanted material from a block






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






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






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






9. A schematic representation of a process






10. 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






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






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






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

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






16. 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






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






18. Sliced CAD data and cuts each layer from a roll of material using a laser or plotter cutter. Sliced layers are glued together to create model.






19. An adverse food- induced reaction that does not involve the immune system






20. A condition whereby users perceive more aesthetically pleasing designs to be easier to use than less aesthetically pleasing designs






21. The exposure of protein to heat or acid - which results in irreversible changes that reduce solubility and change optical characteristics






22. The process of discovering a principle. a technical advance in a particular field often resulting in a novel product






23. 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






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






25. The mass per unit volume of a material






26. 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






27. A mixture composed of two or more substances with one substance acting as the matrix or glue






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