Take a wrench with a 2 foot handle. Say it takes 50 pounds
of force at
the end of the handle to loosen a nut.  Take a
wrench with
a 4 foot handle.
It will take 25 pounds of force at the end of the that one's
handle to loosen
the same nut.  That's why cheater pipes work.


Classic beam scale torque wrenches do indeed rely on a
single point load which is why the handle has a pivot pin.
Your comments are correct for click wrenches.

I don't get the why if this is what you mean by beam
scale torque wrench.

Yep that's the style. Scale reading assumes the load is at
the handle pivot pin.
