The Heiwa Challenge
It is assumed at JREF 9/11 Conspiracy Theories Forum that a structure will be crushed, if you drop a piece (1/10th) of the same structure on it and that it is quite normal - no conspiracy. So here is the challenge: Prove it!
Conditions:
1. The structure is supposed to have a certain cross area A and height h and is fixed on the ground. The structure is an assembly of various elements of any type. It can be any size!
2. The structure should be more or less identical from h = 0 to h = h, e.g. uniform density, layout of internal elements, etc. Horizontal elements in structure should be identical. Vertical, load carrying elements should be similar and be uniformly stressed due to gravity, i.e. bottom vertical elements may be reinforced or made a little stronger, if required. Connections between elements should be similar throughout.
3. It is recognized that the structure may be a little higher stressed at h=0 than h=h due to uniform density, elements, etc.
4. Before drop test the structure shall be stable, i.e. carry itself and withstand a small lateral impact at top without falling apart. Connections between elements cannot rely solely on friction.
5. Before test 1/10th of the structure is disconnected at the top at h = 0.9 h without damaging the structure.
6. The lower structure, 0.9 h high is then called part A. The top part, 0.1 h high, is called part C.
7. Mass of part C should be <1/9th of mass of part A.
8. Now drop part C on part A and crush part A (if you can! That's the test).
9. In order to easily repeat the test/challenge drop height should be <1.1 h, i.e. C can only be dropped from 2h above ground on A that is 0.9 h high.
10. Structure is only considered crushed, when >70% of the elements in part A are disconnected from each other after test, i.e. drop by part C on A.
Have a try! I look forward to your structures!
