For a hydraulic machine with pistons at rest, calculate the mass of the load m2 at m1 = 1 kg, S1 = 200 cm2 and S = 800 cm2.

Let’s translate into SI:
s1 = 0.02 m (squared)
s2 = 0.08 m (squared)
Let’s compose the relation:
F1 / F2 = S1 / S2
m1g / m2g = S1 / S2 (Reduce g)
m1 / m2 = s1 / s2
m2 = m1 * s2 / s1 = 1 * 0.08 / 0.02 = 4 kg
