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. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






2. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






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






4. A set of all possible outcomes or events in an experiment that cannot be further broken down.






5. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






6. Energy which a body possesses by virtue of being in motion






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






8. An electromagnetically operated switching device.






9. Test methods used to examine an object - material - or system without impairing its future usefulness






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






11. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






12. Measure of variation equal to the sum of the deviations of each value from the mean.






13. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






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






15. A control circuit in which the system output has no effect on the control






16. Values that possess names or labels






17. The distance the fluid travels through a system in a given period of time.






18. The difference between the maximum and minimum dimensions allowed within the design of a product.






19. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






20. Not having fixed limits; unrestricted; broad






21. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat






22. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






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






25. A system of discrete states: high or low - on or off - 1 or 0.






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






27. The production of electricity in conductors with the use of magnets






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






29. A toothed wheel whose teeth engage the links of a chain.






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






31. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






32. A device used to convert fluid power into mechanical power in the form of linear motion.






33. Values that represent a measurable quantity






34. 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






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






36. 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






37. The transfer of energy by electromagnetic waves






38. The force per unit area exerted by a fluid against a surface






39. The contact of a relay that is open when the coil is de- energized






40. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






41. 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.


42. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






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






45. The flow of electrical power or charge.






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






47. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






48. Any device that controls - either automatically or manually - the flow of a fluid.






49. An activity with observable results






50. A cylinder that can act under pressure in both directions (extend and retract) to move a load.
