How do you find natural frequency of wind turbine tower?
Solve by treating tower as a cantilever beam and lumping some of the tower mass at the top. First find the deflection of the tower, from this find the stiffness. The lowest natural frequency is sqrt(k/m), where m is the mass at the top of the tower plus the 0.23mass of the tower that can be lumped at the end.
What occurs when vibrations through an object match the object's natural frequency?
Any object in absence of external force vibrates with it's natural frequency. When the frequency of the external forced vibration matches the object's natural frequency, we say that resonance has occurred. In this situation the amplitude of the object's oscillation becomes larger. How much larger depends on the amplitude of the forced vibration.
How do you calculate light wavelength to frequency?
To find (wavelength): Divide (speed) by (frequency). To find (frequency): Divide (speed) by (wavelength).
What does it mean when you hear a glass break?
Ultimately sound is the result of something pushing air back and forth. These pressure/displacement disturbances travel to your ear drum and cause you ear drum to vibrate at the same frequency as the object that disturbed the air in the first place did. In the case of a glass breaking, at moment the glass, say hits the floor, the entire glass would vibrate for a very short moment. After it breaks into pieces, the individual pieces would begin to vibrate at their higher natural frequencies. All these vibrations eventually find their way to your ears by way of the air. Also, it means it's time to buy a new glass.
What is the best way to find fingerprints?
the best way to find fingerprints is to use iodine this Crystal is very easy to use you just heat up a very small portion in a glass tube (you can heat up with only the heat of your hand).In that glass tube put in the sample aka paper and the particles will give the iodine a distinctive yellow patch.
How could you find the sound frequency to break a glass?
High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
Where can you find natural quartz crystal in Oklahoma?
ya i found them in my back yard
Where can one purchase a natural quartz crystal ball?
A natural quartz crystal ball is an expensive item to purchase, and a difficult one to find. One can find one at Bey's Rock Shop, The Magickal Cat, and Best Crystals.
Where can you find a dinosaur in London?
The Natural History Museum or scale models in Crystal Palace Park.

How do you get cabin on sims castaway?
find all the necessary items. to make glass fine sand is on crystal island (swim to it from the first island)
What are the prices of a Stuart crystal?
The prices of Stuart crystal depends greatly on the item that is being purchased. This crystal is widely available in the UK and Australia. In the US and Canada one can find a variety of pieces on eBay and some of the prices found were $24 for a wine glass and $65 for a vase.
Where can one find more information about glass drawer pulls?
When buying glass drawer pulls, one should go to home improvement store for a variety styles and prices. Home Depot, Lowe's, Rona offer diamond crystal glass knobs.
Can sound go so high that it can't break glass?
Its not an issue of "high" but yes, sound can break glass. What it is is an issue of resonance, find the resonant frequency of the specific piece of glass then generate that precise tone, hold it long enough, and pow the glass will break.This is easy to do in a lab using a microphone, amplifier, and speaker. The glass naturally vibrates at its resonant frequency when tapped, say with a pencil. Place the microphone and speaker close to the glass at a right angle. With the microphone on the amplifier input and the speaker on the amplifier output, tap the glass. If done right you should hear the tone get louder and louder as the glass vibrates more and more, then suddenly it will break (you might need to adjust the amplifier gain and try a few times before it works).It can also be done in a lab using a variable audio oscillator, amplifier, and speaker. This works the same as the first case, except you will have to sweep the oscillator frequency to find and lock onto the resonant frequency of the glass.For the human voice to do it is harder, but some trained professional singers can and have done it by sweeping their frequency until they hear the glass respond, then holding that note until the glass breaks.
When finding the fundamental frequency of a wineglass do you need to find the glass's percentage volume before each trial?
Yes, since fundamental frequency is based on the standing wave that forms, by changing the amount of liquid you change the length of the medium the standing wave is in, thus the perceived frequency.
Where is a good place to find a crystal?
One can find crystal in crystal veins in the Earth's crust. These veins can be located using mining maps. Quartz crystal is the most common form of crystal and the easiest to find.
How did we find out that sand could be turned into glass?
Fulgurites are formed when lightning strikes sand and a fused glass crystaline shape is formed. The earth was making this natural glass long before man controlled fire.
