It's me being sloppy in the usage of a language which isn't my first one.



Actually, it is me being sloppy.

Torque is really the moment arm times the force (R X F). The force is the same
since the elevator is merely translated from one position to another. The
moment arm increases from the base of the fin to the top of the fin. So it is
the torque that increased, not the "force" per se.

Then again, with a T-tail, the elevator is no longer essentially in rotation,
but also in translation, so there that to consider too...
