How does the speed of sound in steel or aluminum compare with the speed of sound in air?
typical sound velocities (longitudinal waves) in different materials:
air 343 m/s
aluminium alloyed 6380 m/s
aluminium unalloyed 6320 m/s
aluminium oxide 9000-9850 m/s
steel (austenitic) 5650-5850 m/s
steel (ferritic) 5920 m/s
steel casting 5730 m/s
Sound speed is depend on medium. Steel speed has a great speed when compare to the air.
The speed of sound in steel is faster than the speed of sound in air.
Speed of sound is maximum in STeel or solid.. if we compare the speed of sound in different mediums like vaccuum,water,solid..we will find it decreases with maximum in soild then liquid and then vaccuum
The speed in steel is much greater because, although the density of steel is greater than air the forces are much greater. Check out Wikipedia.org, "The World's Encyclopedia" http://en.wikipedia.org/wiki/Sound#Speed_of_sound
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
The minimum speed for cutting steel with an aluminum oxide stone is 35 m/s.
The speed of sound in stainless steel is 5790 m/s.
Speed of sound is directly related to "stiffness". Most plastics are less stiff than steel, so those plastics will have a lower speed of sound than steel.
The answer is steel. Sound has a greater speed in metals.
With a magnet, Stainless steel is magnetic while Aluminium is not.The other answer is definitely correct, aluminum is magnetic and stainless steel is not. The color is also different. When you drop stainless steel to the floor it yields a sound which is quite different when you do the same to aluminum. Stainless steel is brittle while aluminum is quite elastic. Refer to the material properties of metals in machine design books and tables.
The "speed of sound" is not very well-defined; it varies quite a lot depending mainly on the material, and to a lesser extent, the temperature. But to give you a general idea, the speed of sound in air is about 345 meters/second (depending on the temperature, as well as humidity and pressure). For comparison, the speed of light in a vacuum is almost 300,000,000 meters/second. That's between 800,000 and 900,000 times more. But you get… Read More
The speed of sound depends on the density of the medium. IF the density increases the speed increases. So speed of sound through air is less than that through steel rod.
What is the wavelength of a sound wave in steel and an electromagnetic wave in vacuum having a frequency of 75 Hz?
-- The speed of sound in steel ranges generally between 3,000 - 6,000 meters per second, depending on the composition of the steel. A 75-Hz sound in steel would have a wavelength of 40 to 80 meters. -- The speed of electromagnetic radiation in vacuum is roughly 300,000,000 meters per second ... nominally 50,000 to 100,000 times the speed of sound in steel. A 75-Hz radio wave in vacuum has a wavelength of 4,000 kilometers.
Aluminum is higher expansion - about 23 ppm/C, whereas steels range from 12ppm/C for alloy steel and carbon steel, 17 ppm/C for stainless 300 austenitic series, and 11 ppm/C for stainless 400 martensitic series
That is because of density.Lead has a high density than steel.
The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.
steel is magnetic and aluminum isn't, plus aluminum is lighter than steel
The speed of sound in any medium is directly proportional to the density of that medium. While I do not know the exact numeric answer to your question I can tell you that the speed of sound in those mediums would be ordered as follows (in ascending order) # River Water # Sea Water # Steel
if the the matter is solid the speed of sound can go up like the case with steel. sound goes through steel at 5X (3,805 mph) the speed of sound in air (761 mph). if liquid, like water, sound slows down a bit. if it's a gas, then it depends on the temperature of the gas or any state of matter. the warmer the faster. the colder the slower.
Sound travels fastest, and best through a solid. eg. steel
1484 metres per second in water and 6100 metres per second in steel.
The speed of sound through glass is 3962 metres per second, which is about 13000 feet per second. In normal air, sound travels at a speed of 343 meters per second and in water the speed is 1,433 metres per second. Sound travels at a speed of 5,000m per second or 11,160miles per hour through steel. The speed of sound is dependant upon the medium through which it is travelling and not on the loudness… Read More
Steel. The density of steel is almost 3 times that of aluminum.
The speed of sound in steel depends greatly on the type of steel. The range is typically 4,500 m/s to 6,100 m/s. This applies only to simple compression waves since shear waves are more complex, but that is a different question. For more explanation, see related links.
If the wheels are steel, a magnet will stick. If aluminum, it will not. If the wheels are steel, a magnet will stick. If aluminum, it will not.
The speed of sound depends only on the material it's traveling through, not on the source of the sound. In general, the speed is higher in more-dense media, like steel, water, and rock, then it is in less-dense media, like air.
Use a magnet, steel is magnetic and aluminum isn't
Steel - strength Aluminum - light weight
The reason they don't make aluminum hammers is because most nails are made of steel and steel nails will destroy the aluminum because steel is a lot harder than aluminum.
-- Each has been independently measured, and the speed of light has been found to be greater than the speed of sound. -- When you see an event that produces a sound ... such as a hammer striking steel ... you see the strike before you hear the clank , because the light from the hammer reaches you before the sound does, on account of the higher speed of light.
They are made of several different metals, including steel, copper, aluminum and silver. Many are made of some sort of core (steel, copper, gut, or various plastics) and then wrapped with aluminum or silver. Often the upper two strings (A and D) are steel, wrapped with aluminum or silver, and the lower two (G and C) are gut or perlon wrapped with aluminum or silver. Try different types of strings to find the sound and… Read More
That is because sound waves travel through particles, and solid particles are closer than liquid/gas particles, thus, logically sound wave will travel faster in steel than in a fluid. :)
The speed of sound in air, of which 78% is nitrogen ~ 340 m/s in water ~ 1560 m/s in steel ~ 6000 m/s Hence, steel is the winner. ===================================
Speed of sound in water is faster than in air. Speed of sound in steel is c = 5930 m/s. That is faster than in air and in water. Speed of sound in water is c = 1480 m/s. It is affected by the oceanographic variables of temperature, salinity, and pressure. Speed of sound in air is c = 343 m/s at 20°C = 68°F. The speed of sound changes clearly with temperature, a little… Read More
Steel is three times heavier and stronger than aluminum
Steel is a ferrous metal, aluminum is a non-ferrous metal
Ferrous metals are iron and steel groups. Of aluminum, nonferrous metals and light. Ironand steel and aluminum are much more resistant to stress. Aluminum, steel and iron ismuch more resistant to oxidizing. Weight of steel and iron is heavier than aluminum. What isthe melting of steel, iron to 1400 degrees Celsius. Melting temperature of aluminum is 658 ° C.
The speed of sound in steel is faster than the speed of sound in air , water , and vacuum. Sound is a vibration that travels through an elastic medium as a wave. The speed of sound in a material depends on the elasticity of the material . Elasticity is the ability of a material to change shape in response to an applied force, and then resume its initial shape once the distorting force is… Read More
the aluminum cans don't attract and and steel attracts because its is made of iron and aluminum is not.
Think about it. Steel is an alloy with aluminum and another metal. Aluminum is pure. So this would mean that aluminum is lighter.
Aluminum is a better conductor than steel. But on a vehicle there is often galvanic corrosion caused by contact between disimilar metals, in example aluminum and steel. So if your battery is grounded say to the steel frame and there is corrosion between the frame and the piece of aluminum you are grounding to then you won't gain anything by grounding to the aluminum.
Depends on the medium it is in, water, air, steel etc.
Answer The question may better be written as, "Which steel is harder than which aluminum?" There are many grades of both, and some alloys of aluminum are actually harder than some grades of steel. For instance, 7075-T6 aluminum at 150 Brinell hardness is harder than low-carbon steel at 120 Brinell. Generally speaking, however, steel is harder than aluminum.
Steel and aluminum cans contribute to the production of anything from cars to paperclips. Aluminum cans are also recycled into a lot more aluminum cans.
Sound needs always a medium for transportation. Therefore in a vacuum in outer space we cannot hear a sound, like they play us in science fiction films. The speed of sound depends on the medium in which it is transported. The speed of sound is slow in gases, like in air. The speed of sound is faster in liquids, like in water. The speed of sound is fastest in solids, like in metal.
Aluminum is used on aircraft instead of steel. This is because the density of aluminum is about 1/3 that of steel (meaning it is lighter). Aluminum is also more ductile than steel, allowing for it to bend or elastically deform without damaging the material.
The speed of sound slows in colder temperatures. The speed of sound is dependent on the medium it travels through. It travels faster in steel than water, faster in water than air and not at all in a vacuum. The molecules have more energy at higher temperatures so the sound waves can vibrate the air faster.
Steel is a harder and more durable metal than aluminum. Therefore, steel doors are often more durable and more difficult to damage than aluminum doors.
No. Stainless Steel will resist contamination from the aluminum when they are used together.
They are not made of steel, they are made of aluminum. Aluminum is very light and is relatively cheap.
