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 specific manufacturing term - sometimes relating to one material group only






2. 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






3. Resources that are naturally replenished in a short time.






4. A short length of extruded pipe for use in blow moulding






5. 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






6. A brand is a product from a known source (organization). the name of the organization can also serve as a brand






7. The ability of a material to withstand pulling forces.






8. 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






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






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






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






12. 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






13. 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






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

16. X and Y axes for cutting e.g. CNC Lathe






17. The smallest part of an element that can exist chemically






18. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






19. The aspect of ergonomics that deals with body measurements - particularly those of size - strength and physical capacity






20. This covers all activities from design to documentation. It also includes the regulation of quality of raw materials - assemblies - products and components - services related to production - and management and inspection processes.






21. The reduction of weight and ise of materials






22. A 2D physical anthropometric model based on a specific percentile - which is used with drawings of the same scale as the model to consider the relationship between the size of an object and people






23. Waste water generated from processes such as washing dishes - bathing and laundry






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






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






26. A flexible computer- operated machine that is able to perform a range of tasks in an efficient and accurate manner






27. Computer simulation of a variety of mechanical and biological aspects of the human body






28. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






29. The most efficient way of designing and producing a product from the manufacturer's point of view






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






31. 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






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






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