  2. 1. What uses liquids to provide mechanical power?

  3. Hydraulics.

  4. 2. What deals with the use of gases for mechanical power?

  5. Pneumatics.

  6. 3. What uses both liquids and gases for power?

  7. Pneudraulics.

  8. 4. What can both liquids and gases be classified as in pneudraulic systems?

  9. Fluids.

  10. 5. What states that external force applied to an enclosed liquid will be transmitted throughout the liquid?

  11. Pascal’s Law.

  12. 6. What states that the volume of gas is inversely proportional to its pressure if its temperature remains the same?

  13. Boyle’s Law.

  14. 7. What states that gases expand or contract in direct proportion to changes in temperature if their pressure remains constant?

  15. Charles’ Law.

  16. 8. What is based on the fact that liquid displaced in one area must be relocated to another area allowing a small input effort to be multiplied and applied to an output mechanism in pneudraulic systems?

  17. Mechanical Advantage.

  18. 9. What causes turbulence to increase and creates loss of energy?

  19. A venturi.

  20. 10. What stores hydraulic fluid in a pneudraulic system?

  21. The reservoir.

  22. 11. What pneumatic component permits fluid flow in only one direction?

  23. A check valve.

  24. 12. What component stores fluid under pressure to dampen power surges and provides emergency power in the event of pump failure?

  25. The accumulator.

  26. 13. What is the direction of hydraulic fluid in a pneudraulic system controlled by?

  27. The selector valve.

  28. 14. What pneudraulic component transforms fluid pressure into mechanical movement?

  29. An actuating cylinder.

  30. 15. In which check valve does fluid enter an inlet port, overcome spring tension, and force a cylinder off its’ seat allowing fluid to pass?

  31. A cone check valve.

  32. 16. Which check valve uses a follower to push a ball against a seat?

  33. A ball check valve.

  34. 17. In which actuator does fluid enter and activate a piston and compress a spring that later returns the piston to its’ original position?

  35. A single-acting actuator.

  36. 18. In which actuator does fluid enter one port and push the piston to the other end of the cylinder activating the mechanism attached to the piston rod?

  37. A double-acting actuator.

  38. 19. What type of force is a turning force that tends to produce rotation?

  39. Torque.

  40. 20. What describes a measure of the tendency to produce rotation?

  41. Applied torque.

  42. 21. What describes the tendency to resist rotation?

  43. Resisting torque.

  44. 22. What states that two equal forces acting on an object on the same line of action in opposite directions will cause it to remain at rest?

  45. Condition of Equilibrium.

  46. 23. What do we call a straight line from the axis of rotation to the point where the force causing rotation is located?

  47. The moment arm.

  48. 24. What do we call a toothed wheel used to transmit torque by use of interlocking teeth?

  49. A gear.

  50. 25. What gear is used to transmit power to another gear?
