No they are not the same: If the load in No.1 is 40 the drawing is
correct. If the load in No.2 is 20 the drawing is incorrect. In no.2
with load 20 the pull on the top will be 20 not 40.

Absolute nonsense. In No. 2, there are *two* 20-pound loads. Do you maintain
that the anchor at the top supports only *one* of them?

See my experiment that I used to confirm the theory. It confirms what
I just said.

Your experiment confirms nothing except your own inability to take accurate
measurements. Your numbers were all over the map.
