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 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






2. The type of charge an atomic particle has






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






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






5. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






6. Impeding effect exerted by one material object on another.






7. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






8. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






9. A circuit in which all parts are connected end to end to provide a single path of current






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






11. 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.






12. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

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






14. The geometric center of an area.






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






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






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






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






19. The fixed point around which a lever rotates.






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






21. An energy source that will never run out






22. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






23. The resistance that one surface or object encounters when moving over another.






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






25. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






27. A valve that allows flow in one direction but prevents flow in the opposite direction.






28. A measure of a fluid's thickness or resistance to flow.






29. Used to transport fluid in a circuit






30. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






31. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






32. Anything for which a person is legally bound or responsible






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






34. The unit of potential difference symbolized as V






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






36. 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.






37. Degree of conformity of a measure to a standard value.






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






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






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






41. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






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






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






44. 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.

45. Changes one form of power to another






46. A vector quantity that includes the speed and direction of an object.






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






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






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






50. A part or element of a larger whole
