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:1045 surgical steel.

There are many ways to sharpen knives. I guess your question is whether to use the steel that comes with knives, or a stone. Steels are only to straighten the edge, which is stropping. They won't sharpen a truly dull knife. For that you need a real sharpening system, of which a whet stone is one. The edge of a knife will get wavy with use - that's what the steel is for, to true it back up.

Q:What are the dimensions of steel coils used in the HVAC industry?

The dimensions of steel coils used in the HVAC industry can vary depending on the specific application and requirements of the system. However, there are standard dimensions that are commonly used. One common dimension for the width of steel coils used in HVAC systems is around 24 inches (or 2 feet). This width allows for efficient airflow and heat transfer within the system. The thickness of the steel coils can also vary, but a common range is between 0.020 inches to 0.060 inches. Thicker coils may be used for heavy-duty applications or systems that require higher performance, while thinner coils are suitable for lighter-duty or more cost-effective systems. As for the length of the coils, it can also vary depending on the specific needs of the HVAC system. Coils are often produced in standard lengths, such as 50 feet or 100 feet, but they can be customized to meet specific requirements. It is important to note that these dimensions are just general guidelines and can vary depending on the manufacturer, supplier, and specific HVAC system requirements. Consulting with industry professionals or manufacturers can provide more specific information on the dimensions of steel coils for a particular HVAC system.

Q:i am working a client.my vendor specified in pipe specification pipe line class as MS1 (code for Mild steel)but assigned material to this code is cs smls astm A 106B.my question is any difference between CS and MS material?pls suggest me

*Carbon steel, also called plain carbon steel or Mild Steel, is steel where the main alloying constituent is carbon. The AISI defines carbon steel as: Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. If it crosses limit as said, it will come under alloy steel. ASTM A 106 gr B is a carbon steel pipe and seamless Pipe for High Temperature Service. So, it will be a mild steel comes under carbon steel category.

Q:I was wondering whether anyone knew if painted steels rusts at the same speed as steel that isn't painted. Also, does steel rust quicker than aluminium?Thank you

Rust is the process of steel oxidizing when in contact with oxygen, this reaction can be much fast if certain components are present, such as wet air or water. However, if the paint completely isolates the steel from the environment, the encompassed steel will never rust as long as paint shields it. Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion. Aluminum oxide corrosion also looks a lot more like aluminum, so it isn't as easy to notice as rusted iron.

Q:How are steel coils inspected for bendability?

Steel coils are inspected for bendability through a combination of visual examination, mechanical testing, and dimensional analysis. Visual inspection involves identifying any visible defects such as cracks, dents, or surface irregularities that could affect the coil's bendability. Mechanical testing is conducted to measure the coil's resistance to bending and evaluate its flexibility. This includes performing bend tests to determine the coil's ability to withstand a specified degree of bending without breaking or cracking. Additionally, dimensional analysis is performed to ensure that the coil meets the required thickness, width, and length specifications, as these factors also impact its bendability.

Q:How are steel coils inspected for camber using laser profiling?

Steel coils are inspected for camber using laser profiling, which is a non-contact measurement technique. Laser profiling involves the use of a laser beam that is emitted onto the surface of the steel coil. As the laser beam moves across the coil, it creates a profile of the coil's surface, capturing precise measurements. To inspect for camber, the laser profiling system scans the entire length and width of the coil, capturing data points at regular intervals. These data points are then analyzed to determine the deviation from a straight line, which indicates the presence of camber. During the inspection process, the laser profiling system compares the measured profile of the steel coil to a reference profile, which represents an ideal or straight surface. The deviation between the measured profile and the reference profile is calculated, and if this deviation exceeds a predetermined threshold, the coil is flagged as having camber. Laser profiling offers several advantages for inspecting steel coils for camber. Firstly, it provides a non-contact measurement, eliminating the need for physical contact with the coil and reducing the risk of damage. Additionally, laser profiling is highly accurate, capable of capturing even small deviations in the coil's surface. This ensures that camber is detected reliably, allowing for necessary corrective actions to be taken. Overall, the use of laser profiling for inspecting steel coils for camber ensures efficient and accurate detection of this defect, enabling manufacturers to maintain high-quality standards and deliver reliable products to customers.

Q:What are the common methods of cutting-to-length steel coils?

The common methods of cutting-to-length steel coils include shearing, slitting, and sawing.

Q:can you play one?

Yessir. No, I can only play a piano and Guitar Hero.

Q:A friends of mine says he has balls of steel and i told him i would melt em off with lava. He said it wouldnt work. i disagree

Standard steel melts around 1400-1500 C. Erupting lava can be as hot as 1600 C. There are various types of steel with different melting points though, and the temperature of lava varies widely, so your question can't really be answered definitively. Some lava is definitely hot enough to melt steel though, so you are right and your friend is wrong. :)
