Principles Of Engineering

Subject : engineering
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 opposition that a device or material offers to the flow of direct current






2. A support that prevents translation in any direction






3. Used to control which path fluid takes in a circuit.






4. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






5. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






6. A support that only prevents a beam from translating in one direction.






7. The difference between samples






8. The fractional increase in a material's length due to stress in tension or thermal expansion






9. An inclined plane wrapped around a cylinder - forming the path and pitch.






10. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






11. The total length of path over which the particle travels.






12. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






13. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






14. Changing one form of energy to another






15. The total pressure exerted on a system - including atmospheric pressure.






16. A device for making - breaking - or changing the connections in an electrical circuit.






17. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






18. A negative temperature coefficient - also known as a thermistor - is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature.






19. A result of a force moving an object a certain distance






20. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






21. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






22. The measurement of how difficult it is for charges to flow through a material






23. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






24. A subset of a sample space






25. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






26. The resultant of a system of force is the vector sum of all forces.






27. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






28. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






29. The reason for which something is done or for which something exists.






30. Arithmetic average






31. Any alteration of shape or dimensions of a body caused by stresses - thermal expansion or contraction - chemical or metallurgical transformations - or shrinkage and expansions due to moisture change






32. Slender straight pieces of a truss connected by joints.






33. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






34. A switch that can provide variable motion control






35. An electromagnetically operated switching device.






36. A tool for systematically ranking alternatives according to a set of criteria.






37. Middle value of a set of values arranged in order of magnitude.






38. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






39. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






40. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






41. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






42. Plant materials and animal waste used especially as a source of fuel.






43. The condition of a string - wire - or rod that is stretched between two points






44. The return to the input of a part of the output of a machine - system - or process






45. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






46. A part or element of a larger whole






47. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






48. Two different sized circular objects that are attached together and turn as one.






49. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






50. Graphical representation of a material's mechanical properties
