Learning  Objective: Recognize the  principles  and  components of  hydraulic  systems. 3-44. Which of the following is NOT a component of a hydraulic system? 1. A  reservoir 2. A pump 3. Control  valves 4. A  thermostat 3-45. Which  of  the  following  components is the fluid storehouse for the hydraulic system? 1. Hydraulic  cylinder 2. Accumulator 3. Reservoir 4. Fluid box 3-46. The  baffle  plate  in  the  hydraulic fluid  reservoir  does  NOT  allow which  of  the  following  conditions to  occur? 1. The  dissipation  of  air  bubbles 2. The  settling  of  contaminants 3. The  cooling  of  the  return  fluid 4. An  excessive  formation  of  air bubbles 3–47. Which of the following components creates the flow of fluid within the  hydraulic  system? 1. The  hydraulic  cylinder 2. The  control  valve 3. The  hydraulic  pump 4. The  strainer 3–48. Hydraulic  controls  should  be operated  smoothly  to  eliminate any  jerking  motion  that  causes rapid  wear  of  mechanical  parts? 1. True 2. False 3-49. The force created by a hydraulic cylinder  is  determined  by  the pressure of the fluid and what other  system? 1. The size of the hydraulic hoses 2. The speed of the engine 3. The area of the piston contacted by the fluid 4. The skillful use of control valves 3–50. What  type  of  hydraulic  cylinder exerts  force  in  only  one  direction? 1. Single-acting 2. Double-acting 3. Triple-acting 4. None of the above 3–51. Foreign  material  exposed  on hydraulic  rams  can  damage  seals and wiper seals. 1. True 2. False 3-52. When  performing  pre-  and  post- operational  inspections,  you  should inspect  hydraulic  hoses  for  which of  the  following  conditions? 1. Cracking  only 2. Rubbing  and  cracking  only 3. Twisting  and  rubbing  only 4. Twisting,  rubbing,  and  cracking 3-53. Which  of  the  following  components performs   the work of two shutoff valves  and  a  tube  coupler? 1. Pressure  relief  line 2. Relief  valve 3. Quick-disconnect   coupler 4. Oil  strainer 3-54. What  component  installed  in  a hydraulic system is used to absorb shock? 1. Shock  absorber 2. Accumulator 3. Piston  seal 4. Control  valve 21
