Q: describe the benifits and disadvantages of the using steel as a material for fasteners: Relatively cheap, strong, and non-toxic. For Carbon Steel alloys rust and corrosion are problems. For stainless alloys, cost becomes the problem [and corrosion is not eliminated]

Q: How are steel coils used in the manufacturing of structural components?: Steel coils are used in the manufacturing of structural components as they are typically used to form and shape various structural elements such as beams, columns, and trusses. These coils are unwound, flattened, and then processed through a series of machinery to be cut, shaped, and welded into the desired structural component. The steel coils provide a reliable and strong material base for the manufacturing process, ensuring the durability and stability of the final structural components.

Q: I would like to know if steel is basically a very dense crystal, or if it is a different atomic structure: Steel is made of billions, trillions of very small crystals. This is true of most metals. In order to see the crystal structure of steel, you usually need to cut a sample of it, grind and polish the cut face smooth, then etch the steel with a mixture of nitric acid and alcohol. Without polishing and etching the crystals aren't visible- it just looks like smooth solid metal. Also, in most cases the crystals are small enough that you need a microscope to see them clearly after etching.

Q: Does te game end with broken steel? What is broken steel? I bouht it cuz my buddy said I should.: Broken Steel is an addon that lets you continue the story after the business with the final battle for the Purifier and extends to level cap to... 30? 40? Can't quite remember. In Broken Steel you side with the BoS to wipe up what is left of the Enclave in the Capital Wastelands, in the end infiltrating and (possibly) destroying a huge armored crawler-base (or you can blow up the Citadel, the BoS HQ, your call). Anyway the game won't end after your final decision and you can continue wreaking havoc over the wasteland, exploring, whatever.

Q: How are steel coils used in the manufacturing of garage doors?: Steel coils are used in the manufacturing of garage doors as they provide the necessary strength and durability required for the door panels. These coils are formed into various shapes and sizes to create the panels, which are then coated and insulated to enhance their performance and appearance. The use of steel coils ensures that the garage doors are sturdy, long-lasting, and able to withstand the daily wear and tear associated with regular use.

Q: So...that means Wolverine can stab him, right? Because Adamantite is stronger than steel. Correct?: I don't think Wolverine could stab Superman. The name Man of Steel is just a nickname that was acquired through the years. Just like Superman is able to fly, but when the initial comic came out, he could only, leap tall buildings with a single bound, and is stronger than a locomotive. Of course, now he can fly and is MUCH more stronger than a train! hahahahah. So even though Wolverine is cool, I hardly doubt he could stab Superman...not that he would of course. =)

Q: What are the end uses of galvanized steel coil? What is the market like for this raw material? Would something like this be expensive?Also can you explain: PPGI.And the following specifications; what do they mean/represent?Required Composition :Thickness- 0.23mmCarbon- Max. 0.01%Manganese- Max. 0.20%Phosphorous- Max. 0.05%Sulphur- Max. 0.01%Silicon- ABT. 2.80 - 3.50%CRGO Quality- Prime QualityThanks: Steel coil is the name given to thinner sheet steel when it is manufactured - it comes out of the machine and is formed into a coil for ease of handling storage and transportation. Thin sheet steel is used for plenty of stuff. It can be slit (cut) into thin strips as well as just cropped and used at one of the standard lengths x widths it leaves the mill. There is a big market for this material. It is used in many construction and engineering applications for things like ducting, boxes, gutters, down pipes, flashings, panels, car bodies etc., anything made of thin steel Galvanising is a flash coating of zinc which improves it's corrosion resitance. Cost wise it is a relatively cheap material. The chemical composition of steel varies, it is mostly iron but has various other elements added or present as impurities that change it's characteristics, depending on the end use. These additional elements can be selected to give better weld ability, hardness, tensile strength, corrosion resistance, flexibility and so on. In many applications excess of these chemicals is undesirable. For example sulphur and carbon are generally better at lower levels. The chemical composition data is contained in a material data sheet and expressed as a percentage of the chemical present and which gives the composition of a particular batch of steel, allowing it to be selected for particular applications and traced for quality assurance purposes. The list you have there shows presence and quantity of other elements in a particular batch of coil. The thickness is 0.23mm, quite thin.

Q: I bought my Gerber Scout for 29 bucks at the local Walmart a couple months ago, and so far it's performed better than any of my previous knives (a couple of low quality Bucks, and a Winchester). However, my friend just bought a 50 dollar Buck knife and I absolutely love it, so I'm debating trading mine in and pitching in a bit of cash for the same kind.What troubles me is the fact that everybody seems to be bashing 440A steel. I hear a lot of bad things about it; how it is soft, chips easy, dull quickly, etc. How bad is 440A steel really, and would it be worth trading in my Gerber plus about 30 cash for a Buck Vantage Pro? Apparently the Vantage Pro uses S30V steel, so is it really that big of an upgrade, from 440A to S30V? Thank you.: 440 steel is fine for most knives, but there are better quality steels out there for specialized uses. If you like the knife you have, don't worry about what other people say. If you like the new knife more, trade for it. Sometimes I question why people have to ask so many questions about what's better than what.

Q: What kind of insulation should be used in a steel building?: Vinyl fiberglass insulation is getting popular with the steel building industry. The vinyl fiberglass insulation offers a shining look to the building and is resistant to dust as well as condensation. Effective ventilation inside the steel building can also help in preventing the condensation process inside the building. Besides, the building doors should be insulated effectively so as to minimize the heat loss. Be sure to seal all the door gaps in the building. All these steps are necessary to follow to get an effectively insulated steel building.

Q: for my engineering project I have been asked to design a method of suspending a TV of weight 14Kg from a gantry, the TV must be 5m below the gantry. My team have decided to use as a suspension method a steel cylinder of outer diameter of 10cm and an inner diameter of 8, however we now need to work out both the max stress and strain and the actual stress and strain. and help would be useful: In most engineering calculations we have to make some assumptions about ideal behavior of a material otherwise we would not be able to simplify our equations to manageable sizes. Your steel cylinder (which I'll call a pipe) is made of a certain type of steel. That steel type has property tolerances listed in a steel manual to help you know about your steel before you begin. You'll need to know the cross-sectional area of the pipe and the weight of the TV to determine an average stress on the pipe. Obviously the weight of the TV is the force it generates. The force is its mass x gravitational acceleration. Since we typically think of steel as an elastic material, we think of it stretching like a rubber band or a spring. You pull it down with a TV and it deflects a certain amount, and will return to its original length when the TV is removed. It is typical to assume that all steel, regardless of its strength, has the same value for this elastic property. It is commonly referred to as the elastic modulus. This value will help you determine what type of strain occurs under what type of stress. So, once you have the stress, you can get the strain by using the elastic modulus. Once you have the strain you can determine the deflection based on the pipe length. Having the steel properties will help you determine how close your TV comes to stressing the pipe to its yield stress. If you reach a yield stress, your steel will deflect, but when you take the TV off it will not return to its original shape. I hope I've helped outline some of the things you'll need to do for the project, I tried not to give away specifics so that you can actually engage your brain around the project. Enjoy, learn a lot, and realize that this skill could easily turn into a career where you are designing projects that when done correctly save people's lives every day of the year.
