The surface area of piston A is 2 square inches. Surface area of piston B is 15 square inches.
Force applied at piston A is 10lbs. What is resulting force at piton B? |
A = 5psi
B exerts = 5 x 15 = 75lbs |
|
If piston A has surface area of 10 square inches, and moves 2 inches, how far will piston B move, with a surface area of 50 square inches?
|
50 / 10 = 5
2 in / 5 = 0.4 inches. |
|
A component that transmits force into pressure is commonly called what?
|
A master cylinder.
|
|
What purpose does a restrictor valve serve?
|
To limit the speed of fluid flow in one direction.
I.e. undercarriage down, as it often free falls and could cause cavitation. |
|
State the two types of hydraulic pump in common use?
|
Constant Displacement & Variable Displacement
|
|
In a Constant Displacement system, what component controls the excess pressure in times of low demand?
|
Pressure Regulator.
|
|
A variable displacement pump is able to do what at constant RPM?
|
Vary fluid output to maintain constant pressure.
|
|
The airspeed based system used to provide artificial feel on hydraulic flight controls is called what?
|
Q Feel.
|
|
What is the function of a priority valve?
|
Shuts off non-essential systems in the event of a fluid leak.
