quattro Digest, Vol 6, Issue 18 Re: Torqueing knock sensor/crow's foot

[Larry C Leung]

Reviewing your calculations, you are correct. The 90 degree orientation
of the crow's foot will yield the same torque reading, no compensation 
required. The small angles pretty much still renders any of the
calculated
values moot, however. Unless you have a really short torque wrench.
