Q:How are steel tape measures installed?
Today, I met similar situations at work! Accidentally pull the head, and then automatically can not go back, after opening, winding, after installation, can not automatically withdraw! After a long time, we suddenly noticed that we neglected a small place!
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:Can steel oxidize?????????
Yes - Steel can oxidize, its most commonly called rust Steel is a metal. Depending on the level of oxidation, you might be able to polish it with very fine steel wool. If is is really bad, then you might need a chemical cleaner such as Naval Jelly, which can be found at the hardware store. But the Naval Jelly might discolor the metal, so then you might need to polish it afterward to return its finish.
Q:what are the differences between chrome and stainless steel?
Chrome looks better, but it will eventually rust if it's exposed to enough moisture. Stainless steel will not rust. I would spend the extra money and get the stainless headers.
Q:Steel Pick + Acoustic Guitar = Trashed Guitar?
A steel pick + acoustic on nylon strings = not so good A steel pick + acoustic on steel strings = this might work A steel pick on electric guitar = this might work too I don't think you would trash the guitars, and you probably wouldn't have to worry about being electrocuted...lol... A plastic pick would be so much better. Do they even make steel picks ?
Q:What were some steel advances in industries? 10 points!?
The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
Q:Question for carbon steel ?
None. Mn is a trace impurity in all steels, if you look carefully enough. If you want to find a steel where Mn is not intentionally added, start looking at the alloy composition specifications, there are hundreds of steels. Why are you worried about Mn? Mn is typically added to steels for a very good reason.
Q:What grade of steel is best suited for use on ships. Specifically trawlers?
Best amusing on right here in a while ,simply heading to the harbour bar to look at the fleet are available ,Booboo edged for me ,preferred the Liverpool one ,probably subsequent time we ll inform Chrispen its just a pleasant raid ,however excellent ,the entire equal
Q:what kind of steel is needed for bbq grill?
Bare steel. Galvanized or ANY coated racks will produce deadly chemicals in the food when heated. Galvanizing is a tin coating applied to the surface of the iron. Cadmium is a deadly chemical when ingested and is one of the chemicals on refrigerator racks. I'm not sure about Stainless Steel. The safest way is if in doubt DON'T.
Q:Forge Steel Tools!How Good?
forged steel is a trick to get people like you who know nothing of steel to think of a blacksmith hammering away at a anvil making great tools. Not to say they are bad they are probably fine. but forged just means it was made when the steel was hot, it says nothing of the quality of steel in the process. however whenever steel is forged it will be stronger than the same product made out the same steel, but shaped by machining process.
