In the system illustrated, which of the following readings should be indicated on the pressure gage, if the load (x) is 8000 lbs (3632 kg) and the piston area (y) is 10 sq. in (64.5 sq. cm)? GS-0062

Correct Answer: Option B — 800 psi (56.31 kg/cm2)

Pressure is defined as force divided by area (P = F/A). Given a load of 8,000 lbs and a piston area of 10 square inches, the calculation is 8,000 / 10, resulting in 800 psi. This fundamental hydraulic principle governs the operation of all pressurized fluid power systems aboard vessels.
