In reply to the discussion: North Tower Acceleration [View all]jesters
(108 posts)182. Your post is non-sensical.
Regardless, Greening himself sees the energy expended in fracturing or pulverizing as additional to momentum transfer. That is the main point you need to take home. Plus the point that Ross already states, that even removing those estimates still puts the energy needed for collapse propagation in deficit.
Besides, as I already asked above, why would fracture of concrete be considered part of momentum losses if column strain is not?

Good video! It's certain to generate snark and slander and not much else by way of rebuttal. K&R (nt

Thanks, I think. Lol. But the video still trumps nonsensical Bush Era "science". (nt)

Fortunately the lower section can absorb the energy. A miracle of highrise engineering.
