Take a wrench with a 2 foot handle.* Say it takes 50 pounds

a 4 foot handle.
It will take 25 pounds of force at the end of the that one's

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.
