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 angle of taper - expressed in degrees (usually 5






2. Applies to 3D profiling. it is the amount of tool that passes over work already cut and determines the quality of the finished surface. it is expressed as a percentage - the higher the quality the higher the percentage

12. 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






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






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






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






16. 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






17. 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

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






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






21. Basically a CNC robot with small extrusion head. Moves back and forth along a platform building up a model by feeding heated plastic wire through the head.






22. 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)






23. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






24. The recording of human or animal movement by any means - for example - by video - magnetic or electro- mechanical design






25. The class of materials that are continuous filaments or are in discreet elongated pieces - similar to lengths of thread with a length to thickness ratio of at least 80






26. 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






27. An anatomical 3D model of the human body
