Fluid Power
 
Fill in the blanks:
 
  1.                                   are shapeless substances that take the 
    shape of their containers; they can be liquids or gasses.
 
  2.                                   power is pressurized liquid or gas in a closed system.
 
  3.                                   use pressurized oil or other liquids.
 
  4.                                   use pressurized air or other gasses.
 
  5.  By itself, fluid has no power, but when confined and placed under                      , 	fluid can transmit power that can be stored,               directed and made to do work.
 
  6.  PSI stands for                                           ; it’s the unit    
      of measurement for the force in a fluid power system.
 
  7.  A                                        is a solid cylinder or disk that 
      fits snugly into a larger cylinder and moves under fluid pressure.
 
  8.  By changing the size of the pistons in a fluid power system, we can     
      obtain a                             advantage, that is we multiply the force applied.
 
  9.  The piston that controls the fluid system is the 			cylinder.
 
10.  Fluid power systems                                 power,               power 
	and 					power.

11.  Who is Pascal and what law did he develop?

12.  What are the advantages of fluid power?

13.  List three examples of hydraulic power.

14.  List three examples of pneumatic power.

15.  P= F/A or Pressure equals the Force divided by Area.  How much pressure will a 110 pound         
     lady wearing spiked heels (1/4” square) put on a hardwood floor when standing on one  
     heel?
