Where does a hydraulic press get its extra force?
Fit the components, then test the mechanism.
Pressure change travels through the sealed liquid. A larger output piston gives more force but moves a shorter distance, because the displaced liquid volume is conserved.
Incompressible liquid, negligible friction/leaks, equal base heights. Areas in cm² and strokes in mm.
Lift 150 kg through at least 20 mm.
Compare force gain with reduced output stroke.
