- Q: I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?
- Many people have to jam a cleaning rod muzzle end first, using a hammer to bang out steel cased ammo out of an Ar rifle. This has happened to me 3 times and will Never happen again. It said its harder on the extractor, well that is not so but the case will be badly damaged by the extractor and I don't think that is a good thing for any extractor. Any individual pushing steel cased ammo must be selling it...Don't Buy It!!!
- Q: How are steel coils used in the construction of bridges?
- Steel coils are used in the construction of bridges primarily for their strength and durability. They are shaped and welded into various structural components, such as beams and girders, which provide support and stability to the bridge structure. Steel coils also serve as reinforcement in concrete structures, enhancing their load-bearing capacity. Additionally, steel coils are used for manufacturing bridge decks, guardrails, and other essential elements that contribute to the overall strength and longevity of the bridge.
- Q: How do steel coils contribute to the energy sector?
- Steel coils contribute to the energy sector by being a crucial component in the construction and maintenance of power plants, transmission towers, and renewable energy infrastructure. These coils are used to manufacture equipment like turbines, generators, transformers, and pipelines, which are vital for the efficient generation, transmission, and distribution of electricity. Additionally, steel coils are also used in the manufacturing of energy-efficient appliances and vehicles, further promoting sustainability in the energy sector.
- Q: During fatigue testing of any material (especially for steels), why is strain-control mode preferred over stress control mode?
- because metals, like steel, are ductile and will stretch before breaking. Straining the metal is stretching it, stressing the metal is applying a shearing force or bending until there is an actual metal failure. A sheet metal strap 1inch across and 24 gauge metal is commonly used to support metal ducting systems in construction. These have an average strain to failure weight load as high as 16,200 lbs. As reported by the smacna index, they will safely hold 6800 pounds. Of more interest is the screws used to hold the strap to the duct. While they are grade 3, fairly strong, they strain to 1400 pounds when properly installed, and are safely able to support 650 pounds, unless they are overtorqued (stripped) and this quickly drops to 400 pounds and 125 pounds...big difference.
- Q: days. Use your knowledge of the corrosion of steel and aluminum to predict how they would look different after a week exposed to rainy weather. Explain your prediction.
- Steel rusts, aluminum doesn't so the steel can would be rusty and the aluminum can would not.
- Q: bullets are normally made out of lead...are there bullets that are completely steel?? (not plated)
- They will both knock it over, but it depends on how the bullets hit the block. If the steel bullet hits the block at any kind of an angle, it will knock it over because it will enter the block cross grain. If it hits it straight on, it will not have as much resistance as it goes with the grain of the wood. The rubber bullet will have more resistance because it does not pierce the block. The force from the rubber bullet would be the same no matter what angle it comes from.

- Q: What are the challenges in coil leveling for high-strength steel?
- Coil leveling for high-strength steel poses several challenges that need to be addressed in order to achieve optimal results. One of the main challenges is the inherent hardness and strength of the steel itself. High-strength steel is specifically designed to have enhanced mechanical properties, such as tensile strength and hardness, which make it more difficult to deform and shape. The high-strength nature of the steel requires specialized leveling equipment that can apply sufficient force to overcome its resistance to deformation. This may involve using stronger and more durable leveling rollers or increasing the pressure exerted during the leveling process. Failure to apply the appropriate force can result in incomplete leveling, leading to residual stress and potential dimensional inaccuracies in the final product. Another challenge in coil leveling for high-strength steel is the potential for springback. Springback refers to the tendency of the material to revert to its original shape after being deformed. High-strength steel is particularly prone to springback due to its higher elastic modulus. This can result in uneven leveling and dimensional variations in the coil. To mitigate springback, advanced leveling techniques may be employed, such as overbending or pre-bending the steel. Overbending involves bending the steel beyond the desired level, allowing it to spring back to the desired shape. Pre-bending, on the other hand, involves intentionally bending the steel in the opposite direction before leveling it, counteracting the effects of springback. These techniques require precise control and expertise to ensure accurate leveling. Additionally, high-strength steel often has a more pronounced yield point, which is the stress level at which permanent deformation occurs. This can make it more challenging to achieve consistent and uniform leveling throughout the coil. Proper adjustment of the leveling equipment and careful monitoring of the leveling process are necessary to address this challenge effectively. Furthermore, high-strength steel coils are often thinner and more sensitive to surface imperfections. The leveling process must be carefully regulated to avoid causing damage to the steel surface, such as scratches or indentations. This may involve utilizing softer leveling rollers or implementing protective measures, such as cushioning materials or coatings, to prevent surface defects. In summary, the challenges in coil leveling for high-strength steel revolve around its inherent hardness, springback tendencies, yield point behavior, and sensitivity to surface imperfections. Overcoming these challenges requires specialized equipment, advanced leveling techniques, precise control, and expertise to ensure accurate and high-quality leveling results.
