Q:Warhammer 40k:Steel Legion?
The stock at various shops may vary, but you can buy Steel Legion miniatures through the mail order, or the Internet from GW. Cadian troopers are plastic, There are no plastic Steel Legion troops. The plastic models are (a tiny bit) not so horribly expensive as the metallic ones. The minimum requirements for your force vary from mission to mission, but a good start is 1 HQ unit 2 Troop choices. Also, the total points cost of the battle is to be considered. (Usually 500, 1000, or 1500 points.) What you described is one possible choice, although the size of IG squads is 10 and not 20. And you must include a command squad, the commissar is optional. You might change the other 20 troops for a tank, or a squad of Sentinels. Happy gaming!
Q:How lighter than steel is carbon fiber?
Carbon fiber doesn't really refer to a single material (steel doesn't either, but most steels have similar densities). Pure carbon fiber is just that, fibers made of 90+% carbon. Carbon fiber in the context of cars usually refers to carbon fiber-reinforced polymers rather than plain woven fibers. The polymer adds rigidity to what would otherwise just be like a sheet of fabric. The density depends on the polymer used and the ratio of polymer:fiber. For 50% fiber by volume in epoxy, it has a density of 1.6 g/cm^3. Steel has a density of ~7.8 g/cm^3. So, by volume, steel is almost 5 times heavier.
Q:deflection calculations in a steel cylinder?
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.
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:Is steel lighter than iron?
There are lightweight steel alloys that are lighter, for a given volume, than pig iron. The words iron and steel have referred to different materials at different times, and are used in different ways. A steel structure may also be lighter because steel alloys are stronger, in a given cross-section, that iron or other types of steel. For example, a 1-inch bar of chrome-vanadium steel is stronger than a 1-inch bar of 4130 mild steel or pig iron. The more you find out about it, the more complicated it is. But the answer to your question is (a) Yes, and (b) it's all relative.
Q:Will carbon steel knives stick to a magnetic knife strip?
Yes, carbon steels are magnetic. In fact, some stainless steel knives are magnetic as well. Some stainless steel alloys are naturally magnetic and some become magnetic when they are deformed by forging or rolling (check out a deep drawn SS sink and explore where it is magnetic and where it isn't). Depending on the details, some carbon steels can be made harder than the stainless steel typically used for knives (440 alloy) but the carbon steel knives are very much more likely to suffer corrosion. hope this helps
Q:how many persent of manganese in all types of carbon steel?
Not more than 1.65 % of manganese in carbon steel. *Carbon steel, also called plain carbon steel, is steel where the main alloying constituent is carbon. The American Iron and Steel Institute (AISI) defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60 *AISI 1040 is a carbon steel which is having a 0.60-0.90 % of manganese.
Q:whats the difference between weld steel and sheet metal?
Most sheet metal is coated with galvanizing. Not fun to weld on. Most steel for welding use is just carbon steel.
Q:CONNECTING STAINLESS STEEL TUBE (SOLDER?)?
Compression Ferrel connections are the best. for small diameter pipe and tubing. A local hardware shop can supply you with the necessary parts and pieces and can also give you a step by step procedure/self help brochure. This will also allow you to install any valve or t or blank in the piping system. The only tools required will be wrenchs and a tube/piping cutter for this type of installation. Brazing is accomplished by heating the base metal and then the rod. There are different types of brazing rod such as brass, bronze etc.. you will also need a can of flux to coat the rod or you can buy the rod pre-coated. If the seam is flat metal you can use the heat from the brazing tip to make the filler rod follow the direction you want. This also includes vertical such as on an auto body. I would suggest practicing this in a safe area. Always utilize a fire extinguisher, brazing goggles, welding gloves and wear a long sleeve shirt for your protection.
Q:DUCTILE-TO-BRITTLE TRANSITION TEMPERATURE IN STEEL LOW CARBON?
whilst metallic generators make it the technique is watched interior sight the aggregate warmth, Time in the previous the pour. some steels are run in vegetation that mixture in basic terms for solid demanding product. maximum any simple metallic may be greater effective in its hardness via heating and dipping into oils or water then do it over many cases.To make your question undeniable all metallic is simple except they technique it to be greater good or that's hardened via a warmth treating technique at a later date.
