Torque Wrenches

[Bo Young]

>From my interpretation of this thread, I think the point here is that torque
wrenches don't actually measure torque.  Somehow (and after all this thread
I have a killer urge to take a clicker torque wrench apart) what it actually
measures is the applied force.  The torque scale etched on the wrench is
just the measured force multiplied by the assumed constant length of the
wrench.

That about right, guys?
