You really should not post shooting from the hip, I personally think it makes you look bad ... concrete is super strong in compression, just not so good in tension...the steel rebar helps in tension & lateral stability... the concrete in those columns provides all the strength in compression & that's the primary function of the core ...concrete also offers excellent fire proofing much better than steel that is of course unless the steel is covered in concrete like your Winsor tower fire... the concrete did not collapse but the steel did... @ this point common sense tells us you post information that you know very little about... research before you post Buddy... I linked some very informative info concerning the new WTC tower core... maybe you should go back & read it...

When applied to 9/11, the potential energy of the falling 15 floors of the North Tower was fixed. At most those 15 floors had the potential energy to destroy only 15 of the undamaged lower floors at most. That's being generous since the lower floors had much thicker steel.
It was the vertical support steel that varied in strength from bottom to top, not the floors.

Each floor in the twin towers was built the same, same truss system, same concrete pad, same weight--4127691kgs (4550 tons). Through their connections to the spandrel plates along the perimeter and core support columns, each floor supported its own weight and whatever live load it was designed to bear. The force acting on the total weight of each floor was gravity. The load bearing capacity of each floor was independent of that of any other floor. IOW, all the forces acting on each floor were DOWNWARD, as in towards the ground. Which means that if the connections to the vertical support columns failed or were broken, the floor would fall DOWNWARD.

Potential energy is the energy possessed by a body at rest. PE changes to kinetic energy when the body is in motion. The kinetic energy increases with the square of the speed. For instance, an object doubling its speed has four times as much kinetic energy.

The weight of the 15 top floors of the North Tower was 61915359kgs (62 million kgs)
The 95th floor of the North Tower was 351.5 meters from ground level.
The acceleration of gravity is 9.8 m/s

Potential energy = mgh

= 61915359 x 9.8 x 351.5
= 213279837147.3 Joules (213 billion Joules)

When the upper 15 floors (61915359kgs) began to fall, the PE changed to KE, and as the falling mass increased its momentum as it collided with only one floor at a time, it also increased in mass. Neither the vertical support structure nor the floor connections to it could withstand the force of this collision. One engineer calculated that the force of the collapsing mass exceeded the load bearing capacity of each floor by 30 times.

What would cause the default win you are referring to?
You should remember . . . lying to defend mass murderers is a sign of psychopathy.

The Windsor towers did not have fireproofing on the steel which collapsed. Steel which is connected to concrete is not as strong a connection as steel which is connected to steel.
The collapse of the steel framework on the Windsor happened slowly . . . in separate collapses . . . not all at once. When the steel framework fell . . . after burning intensely for hours . . . there were no debris clouds until the steel hit the pavement. The debris fell straight down and was not exploded hundreds of feet outward as happened with the twin towers. https://video.search.yahoo.com/yhs/search?fr=yhs-adk-adk_sbnt&hsimp=yhs-adk_sbnt&hspart=adk&p=windsor+tower+fire+video#id=1&vid=f3a4c5d43f36ff85ff7addc05718bf96&action=view

I was getting a bit concerned about your retention problem... see if you can figure it out...you wrote it...Buddy...

You quote.... "Let's see if Admin lets your indirect insults pass."

In your false scenario the momentum of a falling mass would decrease each time it collided with a floor. Newton's third law explains the equal and opposite reaction which would cause the slowdown. It would be impossible for the floors to fall independently from the center core to which they were firmly attached.
In the fall of both towers, the falling mass was exploded outward and away from the remaining lower floors. There was nothing to destroy those lower floors except the explosives which were being detonated in sequence down their entire length.

You have a problem communicating clearly in English.
Hebrew being your first language must be causing the problem.

emarine

Sorry buddy but I don't speak or understand any Hebrew... same issue you have with facts & physical laws ... you really don't understand my last post?... well then I will clarify for you ... the only way you will ever win anything of valve is by default... I will explain further... the only way you will ever win anything is if you pester the Admin to kick me off OPP...otherwise your victory's are in your mind or what's left of it anyway...

emarine

After all time & energy invested in you... you still don't understand the 3rd law of motion... unreal...

It isn't a "false scenario", it is the mathematics of Newton's laws. It is basic Classical Mechanics.

68250 tons of mass colliding with a 4500 ton floor is a classic case of Newton's 2nd law in action. We are dealing with the collision of a mass in motion that is 15 times the weight of one floor at rest. The connections of each floor to their support could not possibly have withstood the force coming down on them. Each floor was hit one after the other all the way down. Once the collapse began, the building had no chance. The destruction of the twin towers was a classic case of gravitational progressive collapse. If you are ever going to awaken to the truth, you will have to completely abandon the explosive fiction.

How could he possibly understand Newton's laws, E, explosives have blown his mind.

I thought this crude drawing was easy enough to understand without all the technical jargon...all he had to do was follow the "down" arrow in the middle... & think...

You refuse to identify yourself. If you identify yourself you could prove you're not a Zionist shill.
As long as you hide who you are, the stigma remains.
I don't complain to Admin about anything. If Admin reprimands you, it's caused by your disregard for forum rules.

payne1000

It's revealing that you don't explain what you claim I don't understand.
This is what I do understand:

payne1000

You fail to address the fact that Newton's Third Law would cause falling floors to slow down with each floor they collided with . . . not speed up as you claim.
You fail to address the fact that all floors were firmly connected to the massive steel center core which could not possibly collapse straight down.
You fail to address the fact that 80% to 90% of all the upper floor debris was exploded outward hundreds of feet and little was left to crush the lower floors.

Where is the piledriver?
