1.
Both gauges will read the same amount
of
pressure because they are in the same circuit.
2.
Circuit
A
-
Force is equal to pressure times the area on which it is acting. The pressure is the same in
both circuits. The cylinder in circuit
A
is larger than the cylinder in circuit The same pressure times a
larger area will generate the most force.
3.
Valve C
-
Valve
A
is a check valve which keeps oils from returning to the reservoir during pumping. Valve
B
keeps the oil trapped under the
lift
cylinder. Valve C is used
as
a pressure relief valve and as a flow
control valve to let the cylinder down.
