As the founder of
The Heiwa Challenge I have decided to terminate it. Reason is that it is impossible to design a structure A, where a part C of A, when dropped on A, one-way crushes A. Thanks to all participants that tried to prove the impossible.
The knowledge gained can be applied to WTC 1 on 9/11:
At the moment of contact of the WTC 1 upper part C and lower structure, part A, a certain momentum (mass times velocity), energy (momentum times velocity divided by 2) and forces (energy divided by displacement) are involved. Local failures occur in all structural elements involved due to the forces applied, energy is absorbed and consumed, friction forces between failed elements in contact develop, forces and loads are re-distributed, momentums are reduced as outer forces are applied on the parts and the destruction is always arrested after a while.
It is not a static or dynamic solid mechanics problem! It is a structural
damage analysis matter!
The upper part C of WTC 1 can only apply forces on the lower structure, part A, that the upper part C can itself withstand in the first place. As the upper part C and the lower structure, part A, of WTC 1 have identical structures, the upper part C cannot destroy the lower structure, part A, of WTC 1. Part C will destroy itself first.
I have of course described it in my paper at
http://heiwaco.tripod.com/nist3.htm , which many contenders of
The Heiwa Challenge missed.
Anyway - see you in other threads and thanks for your interest in
The Heiwa Challenge!
