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






2. 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






3. An emerging technology that interfaces the user via the sense of touch






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






5. Refers specifically to the computer control of machines for the purpose of manufacturing complex parts in metals and other materials. Machines are controlled by a program commonly called a 'G code'. Each code is assigned to a particular operation or






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






7. Involving the use of sense organs






8. The ability of a material to resist the propagation of cracks.






9. This is the factor in which the machines multiplies the force put into it






10. The mass per unit volume of a material






11. Employs inkjet technology. Linear array of nozzles deposit molten wax on a platform layer by layer to build a 3D model.






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






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






14. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-

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






16. A volume production process involving machines controlled by computers






17. An appearance prototype or appearance model is a physical representation of an object that literally appears like the production product. However - it does not function and is made from wood - foam - clay or other prototyping materials






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






19. A sequence of instructions to describe a set of actions






20. The design contains those implicit features of a product that are recognized as essential by a majority of manufacturers and purchasers






21. A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length - area or volume. The expansivity can be measured as the fractional increase in dimension per kelvin increase in temperature.






22. 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






23. An organic compound that contains aliphatic hydrocarbons - essential for the structure and function of living cells. examples include fats - waxes and steroids






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






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






26. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






27. The calculation and simulation of unknown factors in products using CAD systems. for example simulating the stresses within a welded car part






28. The permanent deformation of a solid subjected to stress






29. Houses and offices designed to function like living organisms - specifically adapted to place and are able to draw all their energy and water from surrounding sun - wind and rain






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






31. The reliance on the knowledge and skills of an expert in the operation of the product






32. 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.






33. An anatomical 3D model of the human body






34. Someone who resists all technological change.






35. 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






36. A computer- based machine or robot that has the ability to learn from information gained through feedback






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






38. The incorporation of gas into a food product. it may be air - which is often beaten in - or carbon dioxide - which can be introduced under pressure (for example - to aerated water) or by the action of yeast (for example - in bread)






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






40. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






41. 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






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






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






44. Tool path cuts straight X and Y paths






45. 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






46. Tool path is determined by individual Z coordinates across the product






47. A 3D representation of an object drawn with the horizontal plane at 30






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






49. The process of recovering the information contained - for example - in the human voice - which had been previously added to a suitable electromagnetic carrier
