Q: Ok, so I'm obsessed with learning how to play the guitar (I preffer acoustic)... I'm a teenage girl that wants to play rock/pop/folk music... I want to learn first how to strum... then eventually how to pick...so what type of string is better? nylon or steel?
You should start with a steel string guitar. Guitars with nylon strings are classical guitars and are used primarily for classical music, which is why you so rarely see a pop singer playing one. Don't worry about your fingers; they will hurt a little for the first week or two whether you have steel or nylon strings and then that will go away forever. You might want to consider using light gauge steel strings (or even extra light gauge) at first to make fretting easier. Good luck.
Q: I'm analysing horse stirrups and would like to know the disadvantages to stainless steel? - thanks
Stainless Steel has more advantages than disadvantages. But u asked for disadvantages so they r as follows i've given common disadvantages more can be found on Google. Disadvantages of Stainless Steel: Stainless steel tends to scratch and dent. Food, grease and fingerprints show very clearly on stainless steel, making frequent wiping and cleaning a necessity. High initial cost Difficult to fabricate, or in other words, it is not as malleable as other metals, say iron, and hence if not fabricated properly, results in costly re-work. Difficult to weld High cost of polishing etc. i.e. adding finishing touches for the market. there are advantages more than disadvantages. But u asked for disadvantages that's why i have given only disadvantages of stainless steel Hope what u want u got.
Q: Steels like YHB-2, MVS-8, and SK-5. Also if you know anything about these steels that would be helpful.
White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.
Q: How are steel coils used in the production of elevator components?
Steel coils are an essential component in the production of elevator components. These coils are made from high-quality steel that is specifically designed to meet the demanding requirements of elevator manufacturing. One of the primary uses of steel coils in elevator production is for the manufacturing of elevator doors. The coils are processed into flat sheets and then cut into the desired dimensions to create the doors. These doors require strength and durability to withstand frequent use and ensure passenger safety. Steel coils provide the necessary structural integrity and resistance to deformation that is necessary for elevator doors. Additionally, steel coils are also used in the manufacturing of elevator cabins. The coils are processed and formed into various shapes to create the walls and flooring of the elevator cabins. The strength and rigidity of steel make it an ideal material for this purpose, as it can withstand heavy loads and provide a secure and stable environment for passengers. Moreover, steel coils are used in the production of elevator shafts. The coils are rolled into cylindrical shapes and welded together to create the structural framework of the elevator shafts. These shafts need to be strong and rigid to support the weight of the elevator and ensure smooth and safe vertical movement. Steel coils provide the necessary strength, stability, and load-bearing capacity for this critical component of elevator systems. In summary, steel coils are vital in the production of elevator components such as doors, cabins, and shafts. Their strength, durability, and versatility make them suitable for creating reliable and safe elevator systems that can transport passengers efficiently and securely.
