- Q:I haven't seen Man of Steel yet, but which one do you think was better? (please no spoilers)
- Well, I haven't seen it Man of Steel but I really see it hard to believe that's better than Superman. To me, Superman with Christopher Reeve is the best movie about Superman ever made. When I first saw it I was amazed. Watching Superman flying for the first time, catching Loise and graving that helicopter before it falls... it was awesome! I loved it! The other movies that followed were bad but this one was amazing. I've seen what other actors have made with the character, but I believe Christopher was the best. He was the perfect man, the perfect gentleman and the best superhero ever. I know that this Superman is for the new generations so it will be more 'real' and more 'suffered' or will have more personal issues dealing with his origins and blah blah blah... and I wish him good luck, but honestly? I stick to the original Superman because whenever I see Christopher Reeve flying around the planet as Superman (hanging from wires-no CGI people!) and I hear that characteristic music I just melt and I'm a child once more. So good luck to the new generation, I really hope they like this new guy and new story, but I'm more than fine with the original version, thank you. Hope it helps! ;)
- Q:What is the role of steel coils in the manufacturing of bridges?
- The role of steel coils in the manufacturing of bridges is to provide a strong and durable material for the construction of various components such as beams, girders, and columns. These coils are made from high-quality steel that is capable of withstanding heavy loads and extreme weather conditions, ensuring the structural integrity and longevity of the bridge. The steel coils are shaped and processed into the desired sections and sizes, making them essential in the fabrication and assembly of bridge elements.
- Q:What are the safety considerations when handling steel coils?
- When handling steel coils, there are several safety considerations that should be taken into account. Firstly, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and steel-toed boots. This protective gear helps to minimize the risk of injuries from sharp edges, flying debris, or accidental contact with the coils. Secondly, it is important to have a clear understanding of the weight and dimensions of the steel coils being handled. Steel coils can be extremely heavy, and improper lifting techniques can result in back strains, muscle pulls, or even more severe injuries. Therefore, it is crucial to use proper lifting techniques, such as bending the knees and keeping the back straight, or utilizing lifting equipment like cranes or forklifts when necessary. Additionally, steel coils can be unstable and prone to rolling or shifting during handling. To prevent accidents, it is crucial to secure the coils properly before moving or stacking them. This can be done by using appropriate lifting attachments, banding the coils together, or utilizing racks or other storage systems specifically designed for steel coils. Furthermore, it is important to be aware of the potential hazards associated with the steel coils, such as sharp edges, oil or grease coatings, or even damage to the coils themselves. It is essential to inspect the coils for any abnormalities or defects before handling them, as well as ensuring that they are stored in a safe and stable manner to prevent accidents. Lastly, proper communication and training are essential when handling steel coils. It is crucial to establish clear communication channels between workers to ensure that everyone is aware of their roles and responsibilities. Additionally, providing training on safe handling techniques, potential hazards, and emergency procedures can help minimize the risk of accidents and injuries. In conclusion, when handling steel coils, it is important to wear appropriate PPE, use proper lifting techniques, secure the coils properly, be aware of potential hazards, and ensure proper communication and training. By following these safety considerations, the risk of accidents and injuries can be significantly reduced.
- Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts)
- steel is not unbreakable. the world trade centers had a steel infrstructure, but were mostly glass and materials with many other flaws. steel is not the top of the rocwell scale(materials rated by thier hardness) when the planes impacted the outside of the buildings, you have to take into account that the planes skins and infrastructure where made of aluminum(too keep weight down) so once the outer skin of the planes was breached, you have to account for the heat created by burning fuel, friction, and the momentum of a vehicle that weighs tons hitting an immovible object. just keep in mind that if you propel a piece of straw at an proper speed, you can have it impale a full grown palm tree
- Q:How do steel coils contribute to strength and durability in manufacturing?
- Strength and durability in manufacturing are enhanced by steel coils in several ways. Firstly, steel possesses inherent strength due to its high tensile strength, enabling it to bear heavy loads and resist deformation. Coiling steel involves hot rolling or cold rolling, which further enhances its strength and durability. During hot rolling, steel is heated to high temperatures and passed through rollers to shape it into a coil. This process aligns the steel's grain structure, resulting in a more uniform material with reduced internal stresses. Consequently, it becomes stronger and more resilient, maintaining its structural integrity even during manufacturing processes like bending, stamping, and forming. In contrast, cold rolling involves passing steel through rollers at room temperature. This process not only increases strength and hardness but also improves the surface finish. Cold-rolled steel coils are known for their smooth and uniform appearance, making them ideal for applications where aesthetics are crucial. Moreover, steel coils can be coated with various protective layers to enhance durability. Coatings like zinc or polymer-based ones act as barriers against corrosion, moisture, and other environmental factors that can weaken the steel. By preventing rust and degradation, these coatings prolong the lifespan of steel coils and the products they are used in, making them more durable and cost-effective in the long term. In summary, steel coils contribute to strength and durability in manufacturing by providing a resilient material capable of withstanding heavy loads and resisting deformation. The hot rolling and cold rolling processes further enhance the steel's strength and uniformity, while protective coatings prevent corrosion and extend the coils' lifespan. Ultimately, steel coils are indispensable components in manufacturing, enhancing the strength and durability of a broad range of products.
- Q:im buying a new guitar,, it has a built in tuner and its semi acoustic (can be plugged into an amplifier) ,, im trying to choose which strings are better ,, steel or nylon..?
- Musical style speaks volumes when it comes to this issue. Those who want high volume will be unhappy with unamplified nylon string guitars. From my perspective, the basic difference between steel and nylon is this: steel strings ring and nylon strings resonate. The volume produced by steel is generally much greater than nylon but, to my way of thinking, the sound resonance produced by the wood of your guitar is largely masked by steel strings. If you have a decently made guitar (generally, around a thousand dollars and up), the sound interplay between the wood and the strings in a nylon guitar is magical across the entire frequency range. With a steel string guitar, the sound produced by the vibrating string overpowers the wood resonance at all but low frequencies. Personally, I'll take a nylon string guitar any day for the sensitivity gained from the interplay between wood and vibrating string.
- Q:what is the densest type of steel ? what is its density ?what is its tensile strength .
- The density of steels ranges from about 7.7 to a bit over 8.0 g/cm^3, depending on the specific type. Some of the tool steels (a group that contains alloying elements such as cobalt, molybdenum, and tungsten) and some of the stainless steels tend to be the most dense. Steels are a very large family of alloys, having in common that iron is the principal ingredient (They are iron-based, and ALL steels are mostly iron, by definition. Nickel-based superalloys such as inconel and hastelloy are therefore not steels). There are other elements present in steel - usually carbon, at a minimum. The range of carbon content for ordinary steels runs from a trace (~.1% or so) up to a maximum of 2%, theoretically, though actual carbon contents above 1% are fairly rare. Many other elements may be added to produce various types of steels having specific properties. In corrosion-resistant steels, carbon is usually present in only minute quantities, with chromium (400 series) or chromium plus nickel (300 series) being the major alloying additions. In the 400 series grades that can be hardened by heat treatment, hardening is accomplished though the combined effects of the carbon and chromium. The 300 series alloys can be hardened (and strengthened) only through cold working (strain hardening). Density has no direct relationship to tensile strength, BTW.
- Q:What are the different types of steel coil finishes for aesthetics?
- There are several different types of steel coil finishes that are used for aesthetics, each offering a unique appearance and texture to the steel surface. Some of the most common types of finishes include: 1. Matte finish: This is a low-gloss finish that provides a smooth, non-reflective surface. It offers a clean and modern look to the steel coil, making it suitable for various applications in architectural and interior designs. 2. Brushed finish: Also known as satin finish, this type of finish is achieved by brushing the steel surface with a fine abrasive material. It creates a subtle, directional grain pattern on the surface, giving it a textured appearance. Brushed finishes are often used in kitchen appliances, decorative elements, and furniture. 3. Mirror finish: As the name suggests, this finish creates a highly reflective surface that resembles a mirror. It is achieved by polishing the steel surface to a high shine using abrasive materials. Mirror finishes are commonly used in architectural applications, such as decorative panels, elevator doors, and signage. 4. Patterned finish: This type of finish involves embossing or etching a pattern onto the steel surface. It can range from simple geometric designs to intricate textures, offering a unique and visually appealing look. Patterned finishes are widely used in interior design, automotive trims, and decorative panels. 5. Textured finish: Textured finishes are created by applying a texture to the steel surface, such as a stucco or diamond pattern. This adds depth and visual interest to the coil, making it suitable for various applications, including wall cladding, roofing, and garage doors. 6. Colored finish: In addition to different surface textures, steel coils can also be finished with various colors. This is achieved through the application of a coating or paint system, which not only enhances the aesthetic appeal but also provides protection against corrosion. Colored finishes are commonly used in architectural applications, such as building facades, window frames, and decorative elements. Overall, the choice of steel coil finish depends on the desired aesthetic outcome, as well as the specific requirements and intended application of the steel product.
- Q:What are the common methods of inspecting steel coils for defects?
- The common methods of inspecting steel coils for defects include visual inspection, ultrasonic testing, magnetic particle inspection, and eddy current testing.
- Q:i have a white spot on my stainless steel stove, its on the part behind the burners where the oven controls are, does anyone know what it may be and how to remove it. i have tried soap and water and stainless steel cleaner but neither worked. thanks!
- Barkeeper's Friend is the bomb for a metal and fiberglass cleaner, if it can be removed, it will remove it. I have no clue what it is thats on there.
