What class lever is a hydraulic jack?
Many hydraulic systems use a 3rd class lever because the output piston (where the applied force acts) can only move (physically) a short distance. Another example would be your own jaw, where the jaw muscles provide the effort force and the “load” is applied at your teeth …
