Or consider a gas turbine engine fuel control. Up until about the early-70s, these were analog hydromechanical computers. They consisted of 3D sliding cams, spinning flyweights, EDM-contoured valves, servo valves, check valves, pistons, levers, pressurized metal bellows, helium-filled coils, etc etc.
