Q:Question about steel type used in bridges.?
It is used for other things besides bridges and that might be a bad use. Corten was used for very tall light standards in the Fort Worth Water Gardens with the clear understanding that it was to be kept dry. As time passed and personnel changed, somebody decided the round base with bolts sticking up was ugly and put dirt and plantings in the basin in the concrete holding the poles. The watering of the plants kept the rust going through the steel and one pole eventually fell, killing two people. The other light poles were removed.
Q:pedal steel guitar...?
I agree with everything that Lester said. Another thought is to consider starting on a lap steel guitar rather than a pedal steel - its related, a little easier to learn on, and less expensive. Once you get proficient on the lap steel, you can move up to the pedal steel. Good luck!
Q:Why are most homes framed of wood rather than steel?
Because it's always been done that way. Never underestimate inertia when asking why new materials/techniques are not adopted. Besides, the cost does not give steel a clear advantage. You can drive a nail anywhere into a stud. With steel, you have to drill your holes precisely.
Q:timber truss versus steel truss?
How about another option - Steel Re-inforced Concrete Beams. Beam planks would span 8.4 metres but to keep the cost down have an I beam support at 4.2m. Concrete is great. It goes on quick, is sound proof, (very nice when it rains or for road traffic), can have gravel laid on top to act as a heat sink for winter sun and can be covered with normal roof steel if you want to hide it. Its also rust and borer free. While you would need good supports for the front and back, although with an I beam you can have a floating front, it is not much more than what is required for a wooden top. Design it right and your roof could be a future floor for the next addition.
Q:material of guns before steel?
The most common was bronze, which was the strongest material that could be cast, at least until the industrial revolution. Until that time, furnaces which could reach temperatures hot enough to melt steel did not exist. The only way to work with steel would have been forging, which means hammering it into shape while red-rot. Obviously, this is not a very practical method for making large thick-walled cannons (though it was done on occasion. Small arms such as pistols and muskets could be easily made of steel by hand forging.) The most practical way to make cannons was pouring molten bronze which melts at significantly lower temperature than steel. Cast iron was also used. Note that Cast Iron contains 3%-7% carbon, compared to steel which only contains between 2% to 0.2% carbon. Due to the excessive carbon content of cast iron, it's melting point is about 500 degrees lower than steel enabling it to be melted with pre-industrial furnaces. Unfortunately, cast iron is also brittle, unlike steel or bronze. This means that a defective or cracked casting could easily explode, sending iron shrapnel everywhere. (Also, maiming and killing the gun crew, an experienced gun crew was as valuable as the cannon itself!) For this reason. Cast iron cannon were usually considered a cheap, risky alternative to expensive but durable bronze.
Q:low density steel?
If a material has a lower density than steel, then it isn't steel.
Q:Different properties and uses of three types of steel?
Steel Uses And Properties
Q:Elastic modulus of galvanized steel?
Aluminum is non ferrous so a magnet won't persist with it, and this is softer than steel. once you have desperate that, if it has previous paint on it, this is particularly helpful to apply a primer that corresponds to the paint you would be utilising the two vinyl or oil based, then paint. this is possibly no longer Galvanized, yet whilst this is, the unpainted floor with have a 2 colour steel Spackle look.
Q:AR 15 223 AMMO brass vs steel?
I won't run steel through my Ar-15,why spend $700-$1200 on a rifle to run some cheap steel case **** in it? That is what an ak or sks is for.
Q:how is structural steel cut?
Most I-beams are manufactured in a factory by rolling the red hot steel billet through several sets of rolls till the I-beam takes it's final shape. All we normally do to a factory stock I-beam is cut it to length, trim the ends, punch out the mounting holes and or weld on shear tabs. Some I-beams like tapered ones are built from scratch in the shop using plate steel. In fabricating in the shop, a plasma cutter or cutting torch is used along with a hydraulic plate shear. Repairs during erection, usually a cutting torch because you are several stories in the air. If the beam has to be taken to the ground, still a cutting torch because on a job site power availability is poor to connect a plasma cutter. Wingman
