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 force that produces or tends to produce rotation or torsion.






2. Energy derived from sources that do not use up natural resources or harm the environment






3. Arithmetic average






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






5. To monitor and control a process so that the quality of the output/product improves.






6. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






7. 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.






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






9. An energy source that will never run out






10. A gear positioned between the driver and the driven gear used to change rotational direction.






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






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






13. A device that holds the compressed air in a pneumatic system.






14. The collection and analysis of numerical data in large quantities






15. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






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






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






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






19. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






21. The tank that holds the fluid in a hydraulic system.






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






23. Frequency distibution graph






24. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






25. An air pump that compresses air into a receiver tank.






26. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






27. The type of charge an atomic particle has






28. A sketch that shows an object's height - width - and depth in a single view.






29. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






30. 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.






31. An activity with observable results






32. The rotating member of an electrical machine






33. Individual fuel cells that are combined in series.






34. Energy caused by the movement of electrons.






35. 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






36. An external force applied to an object.






37. The result of an experiment






38. Change in length of an object in some direction per unit






39. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

40. 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.






41. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






42. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

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






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






45. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






46. Absolute temperature scale






47. The fixed point around which a lever rotates.






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






49. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






50. The measure of resistance to heat flow
