Um....no. It is most certainly a vector quantity.

Please see http://en.wikipedia.org/wiki/Torque , or if you're a stickler
for reliable sources, any elementary physics text like Hailliday and
Resnick, or Sears and Zemansky.

You're mixing concepts. Yes, torque is *related* to power, which is
*related* to energy, which is *related* to momentum (both linear and
angular) but these are all distinct concepts.

Once you've sorted it out we can talk.

Having read the wiki, I don't see much difference
in what I've been saying.

At one point you claimed that you were exerting
torque on a nut if you were *trying* to turn it.
In "common usage", you are correct, but not
according to the definitions in the wiki, which
do agree with my sophomore in high school text
books.

Also, if there are definitions which pertain to
particle or nuclear physics, I'm not aware of them
and don't pretend to be applying them.
Where is Physics Man when you need him?

In all of the wiki, I can find no instance where
if there is no motion there is torque.

Stated the other way, if there is no motion, there
is no torque.

Yes, there are special cases and special definitions
to suit one's specialty be it lever design or
auto mechanics. But from what I've seen, torque
is work in a rotational or angular mode.

Certainly this is what torque is when applied to
the rating of an automobile engine.
