When steel is heated up a lot by fire, does it SAG or does it EXPLODE?

Question

Most of you have used steel cooking pots, exposed to gas
flames, or even an open campfire.

Some of you have even tried oxy-acetylene or arc welding,
to heat up steel to its melting point.

So what do you observe when you heat up steel below its
melting point?

Does it explode violently, or does it simply behave like weak
flaccid rubber and start sagging?

Just remember: popular opinion is NOT always correct!

Hundreds of years ago, most Europeans and so-called
scientists believed that the Earth was flat, and that if you
sailed too far from land, your ship would fall off the edge of
the Earth. Even religious leaders castigated and outcast
anybody who claimed that the sun was not the centre of the
Universe.

narrated by Dr Judy Wood, PhD.

How can air fire cause steel to explode
like that?

Check out this site making fun of loose change:

For example, every single "fact" presented in loose change can be scientifically or otherwise disproven. Those involved did not actually get much into the science behind the attack and the results thereof. I won't get into the details of why this is the case due to the immense efforts required for such proofs.

I will say something about the world being flat. Could anyone prove that it was indeed completely flat? The answer is no. They might be able to prove that an area has above a certain flatness to it, but it's impossible to prove on land that the world is indeed round. One thing that many that thought the world is flat failed to notice what happens on sea. If the world was indeed flat, you would see a spec of the bulk of the ship appear on approach. That is not the case. Often the sails were seen first then the rest of the ship appeared on approach. It's simple why this wasn't noticed, magnification to see this effect wasn't good enough until the past few hundred years. It was only a matter of time until the technology could catch up to theory and bite it.

To answer your question, "does steel explode?"

The answer is that steel never explodes in itself. Other factors are involved to cause this. The energy of many floors above falling a sizeable distance before a high impact collision with lower unaffected floors was quite large. In fact is was enough to be quite violent in noise and damage. It happened again for the next floor but with more energy. At this point the energy of the building fall increased dramatically that the lower floors couldn't stand a chance. They were destroyed on impact.

There is air in the building and a lot of it. A building falling downwards will compress this air and blow out windows. This is just another side effect of releasing so much energy is a short period of time.

The whole idea of the attack was to hit America hard. This isn't the first time that the world trade center was attacked. It was a huge landmark. The terrorist probably though that the death toll might be in the hundreds. Nobody really knew what was going to happen. In a lot of peoples minds, the towers were going to stay standing.. After all, the Empire State building was hit by a B-25. Not far from what happened to the first tower. The problem was that the buildings anti fire protection was removed by aircraft flying into it. The structure was significantly damaged due to the impact. Many supports were destroyed. The fire burned and weakened the remaining supports from jet fuel The buildings simply got to the point where the weak supports left could no longer support the weight of the building and failed catastrophically.

I'm thinking that the terrorists were pleased that their efforts did not only what they had anticipated if successful, but probably exceeded their wildest dreams. Also they probably thought 'oh crap, we might have gone a little too far.'

Answer 3

I am retired now but worked my trade as a boilermaker, pipefitter and welder for 40 years.
Steel can bend , stretch, break.and sag but NEVER explode. The appearance of exploding buildings is no more than the kinetic energy released when the structure collapsed.

Answer 4

Steel heated sags, it does not explode.

Now, please stop using Yahoo! Answers as a platform for your conspiracy theories. And, please back up your "question" and "evidence" with something that resembles a scientific fact.

Thank you for playing. I am sure that there are plenty of parting gifts for you in the lobby.

Answer 5

Maybe it explodes if you use enough Arabic curse words.
