Q: Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale.Compute the probability that the hardness of a randomly selected steel specimen is less than 60. a..462b..333c..500d.2e..750 Question 8 Refer to question 7. Compute the probability that the hardness of a randomly selected steel specimen is between 70 and 75.a..167b..500c..063d..100e..: Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale. That would be... f(x) = 1/(80 - 50), 50 ≤ x ≤ 80 . . . . . 0 elsewhere Consider this following problem.. Compute the probability that the hardness of a randomly selected steel specimen is less than 60. Here, we have... P(x 60) Oh! Know that the mean and the standard deviation of the uniform distribution function are... ? = (a + b)/2 σ = (a - b)?/12 You should get... ? = 65 σ = 75 Now... P(z (60 - 65)/75) = P(z -0.07) Hence, you should get around 0.462. Good luck!

Q: I'm doing a project on stainless steel dining utensils and its a little more difficult than i thought it would be. There are no sites on the web that tells the creator or when it was first used. There's no sites that that i can see of that talk about the history of stainless steel dining utensils, only dining utensils in general. Please help, i can't change my project now ):: The booklet 100 years of WMF (WMF: Württembergische Metallwarenfabrik / Wurttemberg Metal Ware Factory) includes the patent application (or better: trade mark application) for stainless Cromargan Steel for the production of cutlery in 1926. Cromargan was the company's fantasy name for stainless Krupp V2A steel. Page 86 (unfortunately WMF is a German company, the booklet therefore is in German). Has nice pictures anyways. Appendix: I found the text (a bit cut however) in English language (without images and booklet, just HTML). See below.

Q: What are the different types of steel finishes for coil protection?: There are several types of steel finishes used for coil protection, including galvanized, painted, and coated finishes. Galvanized finish involves applying a layer of zinc to the steel surface, providing corrosion resistance. Painted finishes involve applying a layer of paint to the steel surface, offering both aesthetic appeal and protection against corrosion. Coated finishes typically involve the application of a protective coating, such as epoxy or polyurethane, to the steel surface, providing enhanced durability and resistance to various environmental factors.

Q: How do steel coils contribute to the energy efficiency of buildings?: Steel coils contribute to the energy efficiency of buildings in various ways. Firstly, steel coils are commonly used in the construction of roofing systems. These coils are typically coated with reflective materials that help to reduce heat absorption from the sun. By reflecting sunlight away from the building, steel coils can significantly reduce the amount of heat that enters the building, thereby reducing the need for air conditioning and cooling systems. This, in turn, leads to lower energy consumption and reduced electricity bills. Additionally, steel coils are often used in the insulation of buildings. Steel coil insulation acts as a barrier against heat transfer, preventing heat from escaping in colder months and entering the building in warmer months. By effectively insulating the building, steel coils help maintain a consistent internal temperature, reducing the need for heating or cooling systems. This results in lower energy consumption and enhanced energy efficiency. Furthermore, steel coils are known for their durability and longevity. Their high strength and resistance to corrosion make them ideal for constructing energy-efficient buildings. By using steel coils in the construction process, buildings can be designed with thinner walls while maintaining structural integrity. Thinner walls allow for increased insulation space, enabling better energy efficiency and reducing the overall energy demand of the building. Moreover, steel coils are also recyclable, making them an environmentally friendly choice for building materials. The recycling process of steel coils requires significantly less energy compared to the production of new steel, thereby reducing carbon emissions. By using recycled steel coils, buildings can contribute to sustainable construction practices and help reduce their environmental impact. In conclusion, steel coils contribute to the energy efficiency of buildings through their reflective properties, insulation capabilities, durability, and recyclability. By utilizing steel coils in roofing and insulation systems, buildings can reduce heat absorption and heat transfer, leading to lower energy consumption and enhanced energy efficiency. Additionally, the use of steel coils supports sustainable construction practices, promoting a greener and more environmentally friendly approach to building design.

Q: I'v had 5 people at school say steel is stonger than Titanium and some(5) kids at school say titanium stronger then steel but i looked it up on the internet and i got soem web sites that say steel is stronger then titanium and some sites that say titanium is stonger then steel sooooo???? witch one is strongerPS i no tungsten is stronger then steel.... and titanium.................: TITANIUM is stronger than STEEL. For steel:(I am taking high tensile steel)- Material Yield strength(MPa) -1650 Ultimate strength-(MPa) -1860 density(g/cm3)- 7.8 For Titanium:(Titanium is as strong as steel, but 45% lighter) Tensile Strength : 460-615 N/mm2 So, stregth to weight ratio is higher for titaneum. Titanium is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including aluminium, molybdenum and iron. These alloys are principally used in aircraft and missiles as they are materials which have low density yet can withstand extremes of temperature. Titanium also has potential use in desalination plants which convert sea water to fresh water. The metal has excellent resistance to sea water, and so is used to protect the hulls of ships, and other structures exposed to sea water. However, the largest use of titanium is in the form of titanium(IV) oxide, which is extensively used in both house paint and artists’ paint. This paint is also a good reflector of infrared radiation and so is used in solar observatories where heat causes poor visibility. please read below:;;; The tensile strength of a material is the maximum amount of tensile stress that it can be subjected to before failure. The definition of failure can vary according to material type and design methodology. This is an important concept in engineering, especially in the fields of material science, mechanical engineering and structural engineering. There are three typical definitions of tensile strength: Yield strength - The stress a material can withstand without permanent deformation. This is not a sharply defined point. Yield strength is the stress which will cause a permanent deformation of 0.2% of the original dimension. Ultimate strength - The maximum stress a material can withstand. Breaking strength - The stress coordinate on the stress-strain curve at the point of rupture.

Q: What are the common coil packaging materials?: Common coil packaging materials include plastic wrap, stretch film, steel strapping, and wooden crates. These materials are used to protect and secure coils during storage and transportation, ensuring they remain intact and undamaged.

Q: How are steel coils used in the manufacturing of tubes?: Steel coils are used in the manufacturing of tubes by being processed through a series of steps such as slitting, forming, and welding. These coils are slit into narrower strips, which are then formed into a cylindrical shape and welded together. This process allows for the efficient production of seamless or welded tubes, which can be used in various industries such as construction, automotive, and oil and gas.

Q: How do steel coil manufacturers ensure fair pricing?: Steel coil manufacturers ensure fair pricing through various measures. Firstly, they conduct thorough market research to understand the current industry trends, demand-supply dynamics, and competitor pricing. This helps them determine a competitive yet fair pricing strategy that aligns with market standards. Secondly, steel coil manufacturers consider the cost of raw materials, production, and operational expenses to determine a reasonable base price. They also factor in economies of scale, as larger production volumes can lead to lower costs per unit. Additionally, steel coil manufacturers often establish long-term partnerships with suppliers to ensure a stable and consistent supply of raw materials at fair prices. This allows them to maintain a reasonable cost structure and minimize price fluctuations. Furthermore, these manufacturers strive for transparency in pricing by providing detailed quotations that break down the cost components. This helps customers understand the factors contributing to the final price and ensures fairness in the pricing process. To enhance fairness, steel coil manufacturers also consider the specific requirements of their customers. They may offer customized pricing based on factors such as order volume, delivery timelines, and value-added services. This approach ensures that each customer receives a price that is commensurate with their unique needs and requirements. Overall, steel coil manufacturers ensure fair pricing by conducting market research, considering cost factors, maintaining transparent pricing practices, and offering customized pricing options. By doing so, they aim to create a fair and mutually beneficial pricing environment for both themselves and their customers.

Q: What are the common maintenance practices for steel coils?: Common maintenance practices for steel coils include regular cleaning to remove dirt, dust, and other contaminants, inspection for any signs of corrosion or damage, proper storage to prevent moisture and rusting, and regular lubrication of moving parts to ensure smooth operation. Additionally, it is important to handle and transport the coils with care to avoid any bending or distortion.
