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






2. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






3. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






4. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






5. The stress required to fracture a material whether by compression - tension - or shear






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






7. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






8. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






9. 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.






10. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






11. The collection - evaluation - and interpretation of data






12. Conversion of an analog signal to a digital quantity such as binary.






13. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






14. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






15. Ratio of distance traveled by the applied effort and resistance force within a system.






16. The basic unit of electric current adopted under the Systeme International d'Unites






17. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






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






19. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






20. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






21. The measure of resistance to heat flow






22. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






23. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






24. A system that links electricity produced in power stations to deliver it to where it is needed






25. A part or element of a larger whole






26. Absolute temperature scale






27. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






28. A control system that considers the output of a system and makes adjustments based on that output.






29. Not having fixed limits; unrestricted; broad






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






31. A physical quantity that has magnitude only.






32. 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






33. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






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






35. The ratio of the magnitude of the resistance and effort forces applied a system.






36. 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






37. The geometric center of an area.






38. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

39. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






41. 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.






42. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






43. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






44. Conversion of a digital signal to its analog equivalent - such as a voltage.






45. A surface or shape exposed by making a straight cut through something at right angles to the axis.






46. A measure of how easily a material can be twisted






47. A switching device that uses the magnetic field generated by an electrical current for actuation.






48. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






49. The difference between samples






50. A device used to create flow in a hydraulic system.
