I cannot hold a discussion here without ... Heiwa claiming that structures are scale-invariant.
I notice you do not reply to my posts. So it is due to me claiming that structures are scale-invariant? Where? When? Why?
What I claim is that a phenomenon like a structural one-way crush down, that a part C of a structure A (C<1/10A) can crush A, has nothing to do with scale, size or material or structure for that matter.
What I claim is that the phenomenon is physically impossible according to my Axiom:
You cannot one-way crush an isotropic or composite 3-D structure part A by a part C of itself (C = 1/10 A) by dropping part C on part A using gravity. Part C either bounces on part A or gets damaged in contact with part A and is stopped by part A that is also damaged a little. It is quite basic and all due to gravity. Materials, size and particulars of the elements of the structure part A doesn't matter the least. Part C of part A cannot destroy part A.
And you Mackey, NASA engineer, seem incapable of demonstrating the opposite. But you are not alone. Not one JREF poster has managed it.
