tied to the action point of the aerodynamic force in order to maintain the
balance of the moment. In order to make the head of a plane be not down
when flying, there must be a moment that raises the plane’s head up, so that
a horizontal tail is placed at the rear of the fuselage to produce a downward
force, like the scale of the Chinese steelyard, generating the head up torque.
