P11 - pressure Flashcards
1
Q
Why are hydraulic systems better for transmitting large forces than pneumatic air systems?
A
Hydraulic-> force is applied at one end then increased at the other end as the area is decreased so the force is magnified to a smaller point.
2
Q
Pressure =?
A
Pressure = force / area
3
Q
Equarion for pressure?
A
Density x gravity x height
4
Q
Density = ?
A
Density = mass x volume
5
Q
