    Answer: 3002.86kg

    Explanation:

    Hydraulic cylinder diameter = 125mm

    Ambient pressure = 1bar

    Pressure = 2500kpa

    Piston Mass (MP) = ?

    F| (when it moves upward) = PA=F| (when it moves downward) = PoA+Mpg

    Po=1 bar=100kpa

    A = (π/4) D^2 = (π/4) * 0.125^2=0.01227m^2

    Mp = (P-Po) A/g = (2500-100) * 1000*0.01227/9.80665

    Mp=3002.86kg.
