Alloy steel grade 12.9 refers to a high-strength steel with a minimum tensile strength of 1220 MPa. SAE3120 is a low alloy steel containing chromium and molybdenum, primarily used for high-stress parts like gears and shafts. The combination of grade 12.9 and SAE3120 would provide a strong and durable material suitable for demanding applications.

Submarines have to be very strong because when they are deep under water, there is a great deal of pressure exerted on them by the water. A hollow container underwater is not like a fish underwater, since the fish's body is filled with fluids (blood or other bodily fluids) that are no more compressible than the surrounding water is. Air behaves differently, it is compressible, so the hull must be strong.

A natural cluster of wool fibers is called a fleece.

1. Jewelry such as rings, necklaces, and earrings
2. Cutlery such as forks, knives, and spoons
3. Automotive parts like rims, emblems, and grilles
4. Decorative items such as picture frames, vases, and candle holders
5. Electronic components like connectors and pins

The purpose of a pH indicator in the manufacturing of fruit juice is to monitor and control the acidity level of the juice. This helps to ensure that the juice is safe for consumption, as well as to maintain consistency in taste and quality. pH indicators are used to determine the endpoint of the juice processing to achieve the desired pH level for optimal flavor and shelf life.

The heat number refers to a heat lot quantity of steel. This number follows the steel through the production process. Each heat lot is assigned a specific heat number and it is specific for the grade of steel and the production mill. The heat number is not specific to a certain size of steel. Many sizes could be rolled from the same heat number, but usually will have some sort of suffix added to the heat number (e.g. P78323-2 where P78323 may refer to M-4 high speed steel and 2 refers to the second size produced from that heat.) The next time that this grade and size is produced it will have a different heat number and suffix.

The Mercalli scale is advantageous because it provides a more subjective assessment of the intensity of an earthquake based on observed effects on people, structures, and the environment. It conveys how the earthquake was perceived and its impact on society, which can be valuable for emergency response and earthquake preparedness planning. Additionally, it can help in understanding the distribution and extent of earthquake damage in a region.

Iron cannot be decomposed through conventional methods such as heating or chemical reactions because it is an element. It can be broken down into its constituent subatomic particles or transformed into different compounds through nuclear reactions.

Biro ink and chlorophyll are soluble in methylated spirits

Most anything containing a decent amount of carbon can be turned into charcoal. the basic principle is to bake off the impurities (undesired material) and to leave the carbon behind. This can be achieved a couple of ways. By igniting the material and the quenching it once the impurities are burned off but before the carbon burns off. This method is the most basic, however it doesn't always yield the best results as you loose some of the carbon to burning or not all of the impurities will burn off. Or you can bake your desired material. This provides the best end product as none of the desired material is lost to burning and all the impurities are burned off. It does require extra fuel to bake with though and so it can be inefficient. you can supplement the fuel being burned with the gasses that are produced by baking to make the process more efficient. The last method is the Light and burry method. This is a mix of both previous methods. You light your fuel on fire, and once it has produced sufficient heat you deprive the material of oxygen (burying is one of the most common) this will use the heat from the fire to bake it's self. This process can take a very long time depending on the size of the material and the quantity.

Like diamonds, graphite is what's known as an allotrope of carbon. That means it is actually carbon, although it ocurs in a different form in nature. Graphite occurs naturally as an ore; it is considered by some to be a high form of coal, although this reference is uncommon as graphite is hard to light and makes a poor fuel source.

The bursting strength of a corrugated box is typically measured in pounds per square inch (PSI) or kilogram-force per square centimeter (kgf/cm2). The bursting strength of a corrugated box that contains a 20 kg weight will depend on various factors such as the quality of the corrugated material and the construction of the box. It is recommended to refer to the specific specifications provided by the manufacturer for the bursting strength of the corrugated box.

Silk and wool are protein-based fibers, just like hair. When burned, they release a similar odor due to the presence of sulfur-containing amino acids in their molecular structure. This shared chemical composition is what causes the burning smell to resemble that of burning hair.

Alloys are not used instead of pure metals when the desired properties of the pure metal are specific, such as in cases where high electrical conductivity or chemical purity is required.

Yes, mercury was historically used in the glass manufacturing process to produce mirrored glass. The mercury was applied to the back of the glass to create a reflective surface. However, due to the toxic nature of mercury, this practice has been largely phased out in favor of safer alternatives.

Yes, plastids like chromoplasts and leucoplasts are capable of directly manufacturing the chemical substances found within them. Chromoplasts are responsible for producing pigments like carotenoids, while leucoplasts are involved in synthesizing starches and oils.

Aragonite is a type of calcium carbonate that is used in various products such as jewelry, aquarium substrates, and soil amendments. It is also used in the production of ceramics, glass, and cement. Additionally, aragonite is used as a natural gemstone in the manufacture of beads, cabochons, and other decorative items.

Stainless steel, aluminum, and chrome are commonly used metals for automobile trim. These metals are durable, corrosion-resistant, and can be easily molded into various shapes and designs for decorative purposes on cars.

Particle count analysis as per ISO 4405 is a method used to quantify the size and distribution of particles present in a fluid sample. It involves counting and categorizing particles based on their size ranges, typically expressed as the number of particles per milliliter within specific size ranges. This analysis helps in assessing the cleanliness level of the fluid and monitoring the effectiveness of filtration systems to maintain optimal operating conditions.

Craig Venter is a biologist who is known for leading the private effort to sequence the human genome in the early 2000s. He also played a key role in creating the first synthetic life form, a bacterium with a completely synthesized genome.

Rubber bands are made of polymer chains that have the ability to stretch and return to their original shape due to their flexible molecular structure. The long chains of molecules allow the rubber band to stretch and contract while maintaining its elasticity.

Closing the gas tap a little reduces the amount of gas flowing into the burner. This causes a reduction in flame.

To start a paper cups manufacturing business, you need to find a way to acquire the raw paper material. After that, you need to purchase the proper machinery to make paper sheets and the paper cups molding. Information gathered from Anbao Cup manufacturer in China.

In manufacturing, sugar syrup flavoring and coloring are often referred to as additives or ingredients used to enhance the taste and appearance of the final product. These additives can include natural and artificial flavors, as well as food dyes or colorants to create the desired color.

Starting with ordinary silicone rubber sealant add as much ultra-fine graphite powder as it is possible to get the sealant to absorb to make a putty. You will need to add so much that the putty will *almost* no longer be mouldable. Form the putty around a wire and leave to cure. You will now have a carbon rubber electrode. If it does not conduct you have not added enough graphite dust. As some silicone sealant contains fungicide this should not be used on the skin.

Adding lighter fluid to silicone sealant thins it down. It may be possible to do this when making the putty to thin it down and get it to absorb more graphite powder. However I have not attempted to thin the mix in this way and as the lighter fluid stays in the silicone putty after curing *never* use this when skin contact is intended.
