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:What are black steel pipes made of ?
Black Steel or ductile steel pipes are made from scrap for the most part. Galvanized pipes are made from new raw materials and are electroplated to resist rust.

Q:Steel Tensile Strength?
I don't follow your calculations. It seems to me that the piece you show could be made from .01 steel and still be less than a pound. Also, it is hard to get steel thinner than .015 because anything thinner is not very useful. If you made it out of .015 steel and used a high strength steel, it might be useful. You wouldn't be bashing any skulls, but with some spikes on the end, it could do some damage, and protect against knives or other hand weapons. You also won't get any bullet resistance out of anything that thin. If you want to bash skulls and deflect bullets, you have to get up to at least .10 and several pounds. Any weight on your hands slows down the speed of your punch, but this is compensated for by the increased energy of impact carried by the extra mass. Also, having something hard to protect your hands allows for harder hits and more damage to the opponent. An interesting idea, but it would take some testing to figure out the optimum configuration. One problem I see is that it completely encloses the hand, making it impossible to use the hand for anything else. So you would have to put it on and take it off a lot, and there would be cases where you wouldn't be able to put it on when you needed it. For that reason, I would not wear two at one time. I would make it heavier and wear it on one hand for bashing skulls and deflecting weapons, and keep the other hand free for other things.
Q:How do you calculate density of the steel ball in grams per cubic centimeter?
To calculate the density of any object you will always use the formula: Density = Mass / Volume (P=M/V). You have recorded the known values of the mass and the diameter of the ball (sphere), so we have everything needed to calculate the Density. Mass is 66.80g, but we shall need to use another formula to calculate the volume of the sphere. The formula to use is 4/3 X Pi X radius cubed. However, first of all we need to turn your measurement of the diameter of the steel sphere into the radius of the steel sphere (So that it can be substituted in place of the “radius” in the above formula). Simply half the diameter to find the radius. So 2.51 cm divided by 2 is 1.255 cm. Now insert the radius 1.255cm into the above formula. It would be read like this: 4/3 X 3.14159… X 1.255 ¬cubed (OR 4/3 X 3.14159 X 1.255X1.255X1.255), = 8.2798. So, now we know that the sphere has a volume of 8.2798 cm cubed, we can use this number in place of the “V” in the density formula P=M/V, and we can also substitute in the Mass (66.80g). So now P=66.80 / 8.2798, which = 8.07g/cm cubed. Now we know that from your measurements, steel has a density of 8.07g/cm cubed! This is fairly close to the real life average density, which if I remember correctly is around 7.8 g/cm cubed. Just remember, though, that as steel is an alloy it’s density is not standard and varies due to carbon content etc. Anyway, I hope that helped you!
Q:What oil to use on knife steel?
I don't know that steel, or what kind of knife it is, but unless it is a kitchen knife use the same thing you would use on a gun. Use an oil that dries, like Eezox, or use paste wax, or BreakFree, or Corrosion X.
Q:How did the growth of the steel industry influence the development of other industries?
At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)

Q:I buy steel!!!?
..mm where are you located? .. how much steel is a lot of steel to you? .. whats it worth to you? .. do ya want it from salvage sorce, or from milled sorces? There is a lot of it around, even places that would pay ya to haul it off..
