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. A natural resource that cannot be re- made or re- grown as it does not naturally reform at a rate that makes its use sustainable - for example - coal - petroleum and natural gas






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






3. Designing in relation to materials during processing






4. The business of putting an invention in a market place and making it a success






5. 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






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






7. A sugar alcohol with three hydrophilic alcoholic hydroxyl groups. it is an important component of triglycerides (fats and oils) and phospholipids






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 range of users for a particular product or system.






10. A specific manufacturing term - sometimes relating to one material group only






11. The use of computers to aid the design process






12. A 3D drawing that realistically represents an object by utilizing foreshortening and vanishing points (usually imaginary ones)






13. A broad way of categorizing the kinds of market the company is aiming for






14. A schematic representation of a process






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






16. Markets divided up into smaller groups where the purchasers have similar characteristics and tastes






17. Z axis for depth - X and Y for direction of cut e.g. milling - routing - engraving






18. 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






19. 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






20. Reuse of a product in the same context or in a different context.






21. 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






22. Mechanical efficiency is the effectiveness of a simple machine






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






24. 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






25. The reduction of weight and ise of materials






26. 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






27. 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






28. Tool path is circular - which is useful for round and curved objects






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






30. An evaluation of the actual performance of the task or learning objective using the conditions under which it will be performed and the absolute standard for acceptable performances
