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






2. A volume production process involving machines controlled by humans

6. Involves a company both in the development of new products and in selling those products to new companies






7. Pleasures derived from satisfying peoples taste - values and aspirations






8. Attribute listing identifies the key attributes of a product or process and then enables designers to think of ways to change - modify or improve each attribute






9. The spontaneous representation of ideas on paper without the use of technical aids






10. Automated machines that require data to be inputted manually by a trained operator






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






12. The synergistic merging of nanotechnology - biotechnology - information and communication technologies and cognitive science






13. A tool used in the manufacture of parts by moulding - forging - swaging or stamping processes






14. A sugar (a carbohydrate) composed of two monosaccharide molecules






15. 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






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






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






18. 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






19. The feed speed is the rate at which the cutting tools moves in x - y and z paths






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

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






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






25. 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






26. Designing taking account of assembly at various levels - for example - component to component - components into sub- assemblies and sub- assemblies into complete products






27. Clear representations of the final part. They provide a complete set of data for the product to be realized.






28. A material made up of a network of natural or artificial fibres formed by knitting - weaving or pressing into felt
