Interesting blog post at Prusa about lots of filaments… Too bad they didn’t test stiffness

Saw that this afternoon too, and bookmarked it!
Wouldn’t stiffness be a product of tensile strength?
ie in simplistic terms for the purposes of this chart (and not for building bridges) for any give cross section, the greater the tensile strength the greater the stiffness. I guess we just have to watch CNC Kitchen for real world testing!
It seems nature complicates that a bit: Engineering Fundamentals Refresh: Strength vs. Stiffness vs. Hardness | Fictiv.

Ha! I knew the answer was out there somewhere!
