Question

A simple hydraulic press is filled with pure water (ρ_water = 1.0 g/cm³) and has the pistons of 280 cm² and 50 cm² areas each. Initially the pistons are balanced out, then a 65-kg load is placed on the bigger piston so it moves down until a new equilibrium is reached. To what height relative to it's initial level the small piston will rise?

The height of the small piston, h =  

What mass should be placed on the small piston so it moves back to the initial level?

The mass on the small piston, m =
