A simple hydraulic lift containing an incompressible oil is constructed with two circular pistons, X X\,X and YYY, of diameters 12 mm and 60 mm respectively.
A downward force of FX=40 NF_X = 40\text{ N}FX=40 N is applied to piston XXX.
What is the magnitude of the upward force FY F_Y\,FY exerted by piston YYY?
