- Q:911 conspiacy theorists. Can fire melt steel?
- They can't melt that fast At that temperature, the fire caused by the jet's fuel didn't hot enough to melt the concrete steel. As you see in the video the flame took only 20 minutes. The heat is not fast enough to penetrate all fragment of the concrete steel from top to the foundation, steel is not a good heat conductor like the iron. The explosion only took 5 stories, even all flame in all stories will take 4 hours to melt the core - in this case the core is the worst quality alloy which I don't think is used by WTC. The speed of the falling of WTC building was way too fast. It only took about 9.5 seconds. As an illustration, we throw an object - no matter the weight from the top of WTC, let's count how long it takes from the top to the ground as easy as senior high physics. We took the height of as h = 526.3 m, the gravity 9.8 m/s^2 then apply them to the Newton's equations, h = 1/2*g*t^2 then t = sqrt(2*h/g) = sqrt(526.3/9.8) = 7.32 seconds. The difference is just 2.2 seconds. The resistance of the concrete and solid materials should give at least 200% of the fall duration. WTC's 9.5 secs to fall is even faster a ball sliding on its wall from top the ground. I don't know what happened there. But my Basic Physics lecturer at first grade in my college -who concentrates in Materials- said that it is very odd that the flame burning 5 stories (at most 2% of 110 stories WTC) took only 20 minutes to melt the core of 30% after explosion top stories' core. A friend of mine, got summa cumlaude Bsc in civil engineering - concentrated in structure, said that the pan cake fall has never occured before due to fire causes. If the heat is hot enough to melt the core then the building should bend forward at a broad angle because the strain caused by the heat is not uniformly distributed along the building's core - remember steel is not a good heat conductor. I'm not speculatiing, but 9/11 is an odd tragedy
- Q:Steel guitar information for a beginner?
- Hello okorder.com/ I'm not familiar with the brand...it's certainly not commonly played....but it has the features you need for a starter guitar.
- Q:Will painted steel rust?
- Painting a piece of steel will coat it with a protective layer, causing it to not rust (not get oxidised). Aluminum does not rust.
- Q:Surgical Steel Piercing Reaction?
- The chances of a reaction from the stud is minimal. Surgical steel is an alloy specifically designed to make sterile safe surgical equipment. Often made with titanium or nickel, surgical steel is highly reactive and forms an oxidized layer when made. This layer creates a stable surface. The titanium and nickel are both very hard and resistant to scratches which make for easy sterilization. This will help keep your piercing clean. Be sure to follow the directions you receive when you get your piercing and keep it clean.
- Q:About types of stainless steel for knifes.?
- Ok so listen she already likes me what should I say
- Q:What happened to the comic book STEEL??? not the movie!!!?
- The comic book has been long cancelled. You can see Steel in the ongoing 52 miniseries.
- Q:what do you use (wet stone or steel) to sharpen a carbon knife blade?
- There are many ways to sharpen knives. I guess your question is whether to use the steel that comes with knives, or a stone. Steels are only to straighten the edge, which is stropping. They won't sharpen a truly dull knife. For that you need a real sharpening system, of which a whet stone is one. The edge of a knife will get wavy with use - that's what the steel is for, to true it back up.
- Q:Steel Building Construction.............?
- A true structural steel building is composed of steel columns, steel bar joist,steel purlins,steel roof frames,and steel siding. This is all load bearing structural steel. The vulnerable area of a steel building is the exposure of this steel to extreme temps during a fire. Steel becomes weak at high temps and begins to twist and distort like a noodle in hot water. Most all steel buildings now are specified by the architect/engineer to have fire retardant spray applied to the key components to protect against high heat during a fire. Even with that some beams/columns are also wrapped with several layers of type x fire rated drywall. Multi story steel buildings usually have lightweight concrete poured over steel decking for all floors above the ground floor. Any and all penetrations in these concrete floors must be sealed around to stop fire and smoke from spreading from one floor to the next, and fire rated doors at all stairways to each floor. Even ductwork that runs to other floors must have fire rated dampers that close if signaled by a sensor, this stops smoke/fire from spreading through the ductwork. Sprinkler systems are usually required in new structures that exceed at pre-determined square footage by the state you are in. Hope this helps you out.
- Q:Does shooting steel case ammo in a AR-15 ruin/damage the gun?
- Unfortunately, steel case ammo being actually harmful for your AR is a quite popular myth. Steel is less malleable than brass. When you fire a brass cartridge, the brass expands to the chamber walls and helps block any expanding cases from dirtying up your chamber. When firing steel cartridges, the steel doesn't expand as well as brass, so you probably will end up getting a little carbon residue in the chamber. This tiny amount of carbon in the chamber is enough to make extraction of brass cased ammo more difficult. When the brass expands to the dirty chamber after firing steel ammo, it conforms to the carbon residue somewhat, increasing friction. This small amount of friction is sometimes enough to make a normally okay AR malfunction when attempting to eject a fired cartridge. So to give you a short answer, use both! Just make sure to really clean out the chamber after firing steel ammo.
- Q:Best battle-ready katana steel?
- Go okorder.com/ They have a list of the different types of steel and the qualities of them. Bugei Trading sells very good swords. i prefer the Cheness katana simply because they sell a nice sword at a lower price. Currently I use the Cheness Kazi Ko-Katana. It has a shorter blade length with allows me to do the draw properly for the style I practice. Hope this helps! P.S. just for reference, when I hear the term, Battle Ready, it makes my skin crawl. That terminology simply is not used by experienced martial artists. It is like using the word Studio to describe a martial arts school. EDIT: Peter Gun makes a good point about steel. For what its worth, Ive had several Paul Chen katana.
