has any one made scale model of towers burn them with jet fuel?

Question

see if they crumble as on 911

gustuk why cant you just answer my ?? tell me grow up good answer 911 coverup

Answer 1

A scale model will not represent the forces relative to full scale skyscrapers.

Simply put, the kinetic energy is 1/2 the mass times the velocity squared. Now imagine trying to compare the ounces or pounds of a scale model with the hundreds of tons of actual buildings. Just no comparison.

For what it's worth, unprotected structural grade steel beams lose approimately 50% of their strength at 1100 degrees F. This is why they are coated with an insulating material - in case of a fire which might break out in the building.

No building is engineered or built with the premise that a fully fueled, jumbo jet might slam into it at 500 MPH.

If you watch the videos carefully, you'll see that the commercial jet hit the first tower with enough force to blow clean through the entire width of the building - now consider the damage sustained not only to the insulation, but to the steel beams themselves. I would personally have been more surprised if the target floor hadn't collapsed with the weight of some 50 floors bearing straight down on it. The initial impact of the collapsing floor literally hammered the floors out from under it.

If you want to do an experiment to help you to understand the difference between simple weight verses instantanious impact - simply set a nail a short distance into a piece of wood, now place the weight of a sludge hammer on top of it - stand back and watch as nothing happens - even if you put two or three or more sludge hammers on top of the first one. Now simply drop a single sludge hammer on the nail - big difference between the weight of many hammers and the instantanious moment of one, eh?

Answer 2

Scale models would not give you the answer. Even if you managed a fifteen-foot high model, with its important mechanical properties a hundred times smaller, some very important architectural quantities would be ten thousand times smaller, and some quantities vitally related to fire resistance would be a million times smaller. Burning it would prove nothing.

The difficulties in scaling things down, or up, are very well covered in the famous 1928 essay below. It talks mostly about animals, because the author was a naturalist, but the conclusions apply just as well to structures.

Answer 3

i did see a tv program about how the towers were destroyed and why common construction techniques could not hold up against jet fuel.

i don't remember the name of the tv program but i'm sure you could find it with some online research.

please don't try to do this yourself, no point in burning yourself or your house up.

Answer 4

Why would anybody want to want to do a silly thing like that? What towers are you talking about anyway - the Petronas towers?

Answer 5

You'd still rather believe Bush did it rather than believe that these buildings weren't designed to take a plane hit???

Grow up.
