What font are you using? Are you using tabs or spaces for blanks?

Why has your scale got four arms? Wouldn't one be sufficient?

I can see that, but how are the birds calibrated?

I have scales that weigh mass, as gravity is canceled out on both sides, by
balancing.

Perhaps (?) this is clearer:

^ <Fulcrum lever arm

Perhaps (?) this is clearer:
You misunderstand the problem.
____1#_________________10#______________
Five leading blanks.
Four underscores
"1#"
Seventeen more underscores
"10#"
Fourteen more underscores
That's a total of 45 characters denoting the beam and loads.
^
Fifty-one leading blanks
"^"
That's a total of 52 characters denoting the fulcrum.
You have the fulcrum out past the right end of the beam.
When creating or viewing ASCII art, a fixed pitch font is normally
regarded as essential. When using variable pitch fonts, blanks are
usually much narrower than visible characters. I use a fixed pitch
font on my newsreader. So I see your gibberish as gibberish.

balancing.
What you have my boy is an equal arm balance; which compares two
masses, and will balance if they are equivalent in weight.

And what <<you>> have, Don, is an unequal arm balance, which compares
two masses and lever arms, and will balance when the torques are equal
in size and opposite in direction. Once balanced at one location, it
will remain balanced at any other location, on Earth, the Moon, Mars,
etc...

But not in zero gravity, like in outer space, or when falling.

Sure it will remain balanced unless you give it a nudge: 0 = 0. It
just isn't very useful, because it would also be balanced with any
other combination of masses and distances.
