And Greg replied:
Wrong...  A torque wrench measures the force applied at the pivotpoint (ie
end of the wrench) not the force applied to the effort end. A reading of 258
ft.lbs. is the force applied to the end of tool 2079, and since tool 2079 is
a fixed length. The force on the bolt will the same for "ANY" torque wrench
no matter how long it is.  The only differance will be in the amount of force
that you need to apply to the effort end of the wrench in order to acheive
the 258 ft.lbs. at the end of tool 2079.  Since I have only tought physics
for 14 years, I could easily be mistaken, but I think not.  Now could we
"""PLEASE""" end this thread.

Bingo! By definition, Torque equals Force times Distance. (T = FxD). It is a
resultant, not a vector, such as it's force component with which I think it
is being confused. (If you had a wrench 258 feet long, it would only need a
force of 1 pound (applied at its end) to get multipied by the distance to get
the desired 258 Ft Lbs). I'm done with it!
