A little concept called center of gravity may be in need for explaining this...

How do you get 41 kg of diesel to macht <500g of tnt?
Explosives contain their own oxygen, and have LESS energy pr kg than fuel.
Have you heard of fuel air bombs?
They save wegth by using ambient air for combustion.
It does not add credibility to the rest of your teori.

Not really! Newtons Bit is caught with his pants down!
It seems my two years old grand daughter knows better. She has this toy that consist of a board with (2-D) holes of various shapes and then (3-D) blocks of various shapes. The fun is to drop the (3-D) block through the (2-D) holes in the board.
There is one hole that is square and one block that is a cube and the side of the cube equals the side of the square.
Only way to get that cube through that hole is by perfect, vertical alignment of the cube (and that is the fun of it, when you are two years old).
If the cube is tilted a little (as in Newtons Bit's figure), it will never go through the hole (the lower structure). One cube wall (right) in the figure) will go through the hole (the lower structure), but on the other (left) side, the cube wall will be outside the hole (the lower structure left wall).
This NWO sectarian standard that tilted blocks go through square holes promoted by Newtons Bit is really disturbing. You spoil the fun for children to learn real physics.
Well, if that is the case 41 kgs of diesel oil is really more dangerous than 500 grams of TNT. Imagine all these diesel trucks driving around like real bombs.

This would work..... if the the perimeter structure were a continuous solid piece. You sure have a habit of weak analogies. Not very surprising.
Now now don't get your britches tied up in knots. We're not comparing solid blocks of material to an assembly of thousands of pieces. That's your analogy not mine.
That's cheating and ignoring friction and many other things that NIST, Bazant, Seffen and now Newtons Bit are trying to promote. Typical sectarian stuff.
BTW - you can also destroy the cube but it is supposed to be intact by NIST, Bazant and the other clowns.
But I do not blame them really. Look at all these clowns in Washington, DC, and what they are up to these days.
If mixed with air as an areosol or vapour, you will get a nasty explosion.
Smokediver school have a nice example. A 200L drum with a bit of diesel is closed and heated over a fire. Eventually the mix of air and fumes go off sending the drum flying.
If you can´t calculate the energi content of diesel and tnt, you could try search wiki for fuel air explosives.

Regardless and apart from you spoling the fun of my grand daughter - sub-topic was Newtons Bit's attempt to get a tilted square between two vertical, parallell lines separated by the length of the squares side ... and it does not work according Euclides and basic geometry! According Newtons Bit it is evidence that by defintion the columns fall inside the building. To me it is clear evidence that Newtons Bit has got the basics wrong or missed some classes of geometry.
OK, OK, OT, the universe was created only 6000 years ago when the Pyramides were built with dinosaurs still running around. Arkimedes, Euclides, Gallilleo, Newton, Darwin, Einstein are just fools like the rest of us clear thinking persons and when GWB blows up the world a new one will be created the next day. This sectarian nonsense should be diverted to another section of JREF Forum. End of OT.
???? - 41 kgs of diesel oil mixed with air + a diesel engine (and a crane) would have lifted the WTC1 upper block (33 000 tons) up again (3.7 metres) in position. Read my article at http://heiwaco.tripod.com/nist1.htm#53 .
In my business we sometimes lift 2 000 tons blocks. TNT is not recommended, though.
Diesel oil luckily doesn't explode at ambient temperature or pressure but works fine in a diesel engine. Again, do not try to run your diesel engine with TNT.

Heh, tell that to the towers that were collapsing... Apparently they don't really care what their geometry is trying to fit through. If it didn't fit it dislodged or crushed whatever was in the way. If you don't remember, while the tilting was progressing the bottom portion of the loose section was crushing in parts of the lower section...
I'm not even sure that a response is even justified to this any more. You can live with your little fantasy sect world all you want, however in the end your constant bickering over calling every engineer or individual that points out your errors is nothing but a distraction that tap dances around the real issue you aren't making any effort to correct.
It's been stated before that job titles do not equate to competence in the field. You certainly know terminology that I've becomes familiar with but that's about the only indication I've gotten that demonstrates you apparent 40 years of experience.

Well, momentum (kg m/s) is just mass, m (kg), times velocity, v (m/s), and to get the kinetic energy (J or kg m²/s²) of that momentum mulitply with velocity, v, again and divide by 2.
So what is important is the mass, m, and velocity, v.
But you have to get all those loose masses through Newtons Bit's hole and not spill some of the masses outside. Now, when some masses rub against other masses after passing the hole, friction develops and wastes energy (J) and reduces velocity, v. NIST has never heard about friction! So when the WTC1 collapses, all masses above are well oiled and smooth and just flow through the hole and destroys everything below the hole. Magic! Material strength apparently doesn't matter, either.
NWO physics. I really feel sorry for all physics professors in the USA that from now on must teach that garbage. Poor Steven Jones was fired for trying to save Newton.
You don't have to lift the 33 000 tons in one go with a huge CRANE. 1000 pieces of 33 tons each, one after another, with a 35 ton SWL small crane would also do the job and use the same amount of fuel.
You follow? 33 times 1000 = 33 000! That's how it was done in the 60's.
Assuming 1000 kgs of TNT contains 4.2 GJ of energy and 1.2 GJ of energy is required to lift the 33 000 tons upper block up 3.7 metres, it seems you need 350 kgs of tnt to blow the upper block back up again. Safer to use a crane and 41 kgs of diesel fuel, though. The fuel diesel oil contains 8.5 times more energy per kg than tnt. And is much safer to use. That's why I use diesel. For my car! What are you using TNT for? Blowing up banks? Sounds criminal.
What is momentum of mass? No idea. Moment of a mass around a point is the mass times the distance to the point. You mean momentum of motion (mass times velocity)? What has it to with it?
