Reply #20: And trees fall how exactly? [View All]

[plaguepuppy]

Oh of course, they sink straight down into their own root print, I've seen it a thousand times!


" If the tree breaks loose at the stump it will kick backward and kill you."


How many trees have you cut down sonny? You make a big cut on one side (the "asymmetric damage") but leave a big enough hinge for the tree to stay up, then make a small cut on the opposite side to make it fall. And as to towers falling, the picture at the top of the prior thread shows how the tower would indeed topple, somewhat like a tree:



Once the "hinge" region fails the force needed to continue to pivot becomes much smaller, sort of like static friction vs. sliding friction. The rest of that outer tube (236 14" square box columns ties together with 52" tall steel spandrel plates at each floor) will try to follow the path of least resistance by pivoting. Collapsing on its own axis represents the opposite extreme: the path of greatest resistance, like the tree telescoping on itself. In nature things like that don't happen, with or without magic phrases.
