Re: Torque Wrench Adapters

[Crossley Family <crossley@northwest.com>]

Well, this has certainly been a lively thread!  I normally set back
on these kinds of exercises and see who can be the most aggressive, the
most abrasive, the most assertive and the most wrong.  All I can say on
this one is that we have a lot of players! Being a graduate engineer 
product of the early '60s (pre calculator for you younger types), I do
recall that moments, "torque" to you motor heads, is taught in a lower
division statics class and is hardly rocket science.  I was having a
hard time trying to understand why a torque wrench adapter would have
any affect on a calibrated torque sensing system.  Then it dawned on me
that this adapter could connect at the business end of the wrench and
extend radially away from the point of force application thereby
establishing a new business end.  If this is the case then the wrench
torque read out would not reflect the torque applied at the new business
end. The actual applied torque would equal the torque reading multiplied
by the ratio of the combined wrench/adapter effective length divided by
the original wrench effective length.  Now I know I have stirred the
juices of this twisted group and I expect to get flamed, so go for it!
