Why mix rhenium into tungsten?
Mixing rhenium into tungsten improves its high-temperature strength and resistance to wear and corrosion. This alloy is commonly used in aerospace and defense applications where these properties are critical for performance.
Yes, acrilan AKA acrylic is an all-natural fiber. It's an all-natural fiber because it comes from an animal fur or skin.
What is the density of a thick rubber band?
The density of a thick rubber band can vary depending on the specific material and composition of the rubber. However, most rubber bands have a density around 1.0 to 1.2 grams per cubic centimeter.
When was aluminum wiring outlawed in mobile home manufacturing?
About 1976. The problem is that mobile homes are constructed with flimsier walls which will ignite when aluminum overheats. Copper can carry much more of a load than aluminum and therefore is safer.
The real hazard with aluminum wiring is related more to bad connections and improperly completed electrical work.
While aluminum wire cannot handle the flow of electrical current as well as copper, this is corrected by the use of a larger size of wire (as outlined in the CEC or NEC respectively). Therefore, assuming all other factors are taken into account, like correctly sized breakers and properly planned circuits, the wire itself will not have any issues with heating.
However, the same cannot be said of wiring that was done with connectors and devices such as plugs and switches that are not rated for use with aluminum wiring.
Bad connections caused by devices not rated for aluminum wiring or connectors that are not rated, can cause a poor electrical connection, which in turn will create heat. This in turn can cause wires to overheat and burn back from the bad connection and then potentially cause a fire.
Through knowledgeable application of the correct strategies and materials, aluminum wiring is no different that copper wire. Both are subject to heating problems if not connected properly or sized correctly for its application.
But, when installations are completed properly, these concerns are unfounded and aluminum wiring is no less safe than copper.
How do you make your rubber band racer go 20 meters by only using 4 medium sized rubber bands?
To increase the distance your rubber band racer travels, you can experiment with using a larger wheel diameter to cover more ground per revolution. Additionally, optimizing the design for reduced friction and ensuring the rubber bands are wound tightly can help maximize the racer's distance with just 4 medium-sized rubber bands.
What is the description of bath soap?
Bath soap is a cleansing product used during bathing or showering to remove dirt, oils, and impurities from the skin. It usually comes in bar or liquid form and is formulated with ingredients such as surfactants, moisturizers, and fragrances to cleanse and nourish the skin.
Rubber is a polymer composed mainly of carbon and hydrogen atoms, making it highly flammable. When heated to high temperatures, the chemical bonds in rubber break down, releasing energy in the form of heat and light, which causes it to burn. The combustion process involves the reaction of rubber with oxygen in the air, producing carbon dioxide and water vapor as byproducts.
Will a stainless steel cup work as a crucible?
Yes, a stainless steel cup can work as a crucible for some low-temperature melting processes, such as melting small amounts of metals like aluminum or copper. However, it may not be suitable for high-temperature applications involving materials like gold or silver due to the lower melting point of stainless steel. Make sure to check the specific temperature limitations and compatibility of the stainless steel cup for your intended use.
What is the purpose of tempering a quench hardened plain carbon steel?
Tempering is applied to quench hardened plain carbon steel to:
1. reduce brittleness.
2. increase ductility.
3. increase toughness.
4. relieve stresses in the martensite structure.
Increase in tempering temperature lowers the hardness. The reduction in hardness of the quenched steel depends upon the composition of the alloy and the exact value of the temperature applied.
Rubber is a neutral substance, meaning it has no overall charge. However, it can become charged through processes like friction, where it can become negatively charged due to the transfer of electrons.
What are the different parts of a ball point pen?
A ballpoint pen typically consists of a plastic or metal barrel, a retractable mechanism (such as a button or twist mechanism), an ink cartridge containing viscous ink, and a small metal ball at the tip that rotates to transfer ink onto paper. Some pens may also have a pocket clip and a grip section for comfortable writing.
What is formaldehyde used industrially to make?
It is generally used in the synthesis of more complex compounds and materials.

Does a steel wool pad and vinegar generate heat?
No, steel wool and vinegar do not generate heat when combined. The chemical reaction between the two ingredients creates a solution that can be used for various cleaning purposes, such as removing stains or rust.
How to remove white out from nylon clothing?
To remove white out from nylon clothing, gently scrape off excess dried white out using a dull knife or spoon. Then, apply a small amount of rubbing alcohol onto the stained area and dab with a clean cloth. Wash the garment in cold water with laundry detergent and air dry. Repeat if necessary.
Where was the first ever pencil made?
An unknown inventor, probably 2 500 years ago, in the ancient Roma. Having been lost for centuries, it was independently discovered again in the late 19th century in Nevada, USA, by Joseph Cartwright. Cartwright and his business partner, Joseph Dixon, commericalized the product by embedding it inside of wooden sticks cut from the numerous pine trees on Cartwright's ranch. The Dixon-Ticonderosa pencil was thus born and sold throughout the western United States, and it remains a strong player in the global pencil industry to this day.
What does 12 gauge metal weigh?
Sheet steel is 4.375 lb per feet squared; 4.531 lb per feet squared for galvanized steel; Stainless steel is 4.41 lb per square feet; and 1.140 lb per squared feet for aluminum.
Silk is a solid material. It is a natural protein fiber produced by certain insects, such as silkworms, and is commonly used in textiles.
What are chemical properties of stainless steel?
Pure iron (Fe), mixed with carbon to produce 'steel', Chromium is added to steel to make it resistant to rust. copper, Titanium annd vanadium are the alloys which make it more suitable for specific uses,
How do you convert square meters to cent?
To convert square meters to square centimeters, you need to multiply the number of square meters by 10,000 (since 1 square meter is equal to 10,000 square centimeters). For example, if you have 3 square meters, you would have 30,000 square centimeters (3 x 10,000 = 30,000).
How do you check purity of wool?
You can perform a microscopic purity test by using transmitted light to see if the fibers form simple shapes. For example, cashmere's fine fiber will appear as small blocks next to each other. Pure cashmere is always labeled as 100% cashmere and it is soft and slippery, but if it is part silk, it will appear shiny.
How do you convert cubic meters to linear meters?
There can be no conversion. A linear metre is a measure of length in 1-dimensional space while a cubic metre is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
Which alcohol is used in manufacturing of soap?
Ethanol, also known as ethyl alcohol, is commonly used in the manufacturing of soap. It helps to dissolve and mix the ingredients together and also acts as a preservative in some formulations.
Its simple but you need the width of the material you are going to be working with.
LINEAR METRES (LM) = AREA OF SPACE / WIDTH OF MATERIAL REQUIRED(W)
For example:
I have a room 6 x 5 metres so the Area = 30 m2
I want to lay timber floorboard planks and their WIDTH per floorboard plank is 0.25 metres.
LM=A/W = 30/0.25 = 120
Therefore I will need 120 linear metres of the 0.25mtr wide planks.
