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 square root of the variance.






2. The result of an experiment






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






4. 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






5. The collection - evaluation - and interpretation of data






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






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






8. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

9. Used to transport fluid in a circuit






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






11. A quantity that has both a magnitude and direction.






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






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






14. 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.






15. A profession for which one trains and which is undertaken as a permanent calling.






16. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






17. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






18. The type of charge an atomic particle has






19. 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






20. 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.






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






22. An activity with observable results






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






24. 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.






25. 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






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






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






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






29. The measure of resistance to heat flow






30. 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






31. The process of creating an object by adding small pieces or layers together to make a final product






32. 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






33. The probability of an event occurring based upon other event probabilities

34. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






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






36. A dynamo or similar machine for converting mechanical energy into electricity






37. Pressure exerted by a confined fluid acts undiminished equally in all directions

38. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






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






40. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

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






42. 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.






43. A support that prevents translation in any direction






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






45. 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






46. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






47. The unit of potential difference symbolized as V






48. A small circuit board that controls all the processing within a computer.






49. The place at which independent and often unrelated systems meet and act on or communicate with each other.






50. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.
