Some time ago, in a TV column, a player with Lv Feilong called "Roar power" shattered the goblet. That being said, Roar power really exist? What is its principle?
What criteria do you use
If you think, Roar power must be the kind of martial arts - roar of a voice on Feishazoudan, everyone instantly blown away, severe internal injuries to vomit blood. Well, this is certainly Roar power does not however, if you put your request, think shouted a voice, on the broken glass also considered Roar power, so that the Roar power, the reality is there.
The sound of shattered glass can be used, not the first person Lv Feilong abroad was also demonstrated it.
Some people, after a long period of training, plus some of their own talent, such Roar power can be trained.
Shouted a voice, on the broken glass, the vast majority of people are aware that this is because the principle of resonance. From small to large, "resonance" We heard it is too much, such as:
Why are disabled when snow board shouting? Because the resonance will bring an avalanche.
Why soldiers when they march over the bridge, but not marching? Because the resonance will bring the collapse of the bridge.
............
We all know that a lot of disasters resonance is the culprit, but the essence of resonance, what is it?
Essence resonance
Resonant power of infinity. Lived 86 years and never married, it will in eight languages, and with a variety of Edison helpless and tangled Nikola Tesla, in his biography, Tesla had once nonchalantly he told reporters he can go to the Empire State Building, in a very short time it turned into a pile of the rubble. The machinery used is just a tiny oscillator only.
Tesla oscillator using mechanical resonance experiments, had made some of the surrounding buildings had a resonance, and finally he measured the resonance frequency of the house, but he also found the experiment there is a huge danger, otherwise it will not even police have also been attracted.
The real world, small molecule atom, Great Earth, each thing vibrates. But, some vibration slowly, you see, such as butterfly wings, flapping about 5 times per second, we can say that a butterfly flapping its wings in the natural frequency is 5 vibrates slightly faster, such as bees wings 400 times per second, some flapping, then the natural frequency of this bee wings is 400 Hz, you can not clearly distinguish between each vibration bees, but you can hear it, buzzed ......
Swing rocking back and forth is vibration. A man in the swing, you push it aside, if every time he placed the highest point, you pushed him, then the swing will swing very high. This is because you use a frequency with the natural frequency of the swing pushing match, this is resonance.
If the swing has not swing to the highest point, you begin to push you hard with a direction opposite the direction of the swing motion may not only fail to push the swing high, but from the opposite effect.
Above tells us that when the frequency of the external energy with the natural frequency of a certain system of the same, the system will be able to get a steady stream of accumulated energy, which is the resonance nature.
No doubt, it certainly is a sound energy, bees flap their wings rapidly, causing air vibration, the vibration of the air as the water ripples, reached our ears, eardrum receives power, followed by vibration, so we heard the bees flying sound. Lv Feilong make glass shatter, but also the truth.
As long as the natural frequency of the sound emitted Lvfei Long frequency consistent with the glass, glass can achieve maximum amplitude, eventually cracked. Here, the glass vibrations equivalent to "swing" and the external Lvfei Long sound, is pushing the swing of "man."
Resonance hazards
Resonance phenomena around us, everywhere, but the vast majority are too small, we did not find it.
When you start the car, still a certain speed, a component of the car vibrating badly. This is because the result of resonance, when you increase your speed, the resonance disappeared.
When large trucks passing from your door, windows and doors of your home to bang bang sound, which is caused by resonance.
Resonance will produce a lot of harm, so the buildings, bridges and other construction, the resonance factors must be considered.
The following three animated figure, there are three standing shelves, their structure is exactly the same, but the height is different, you can think of it as three different height floor. Each rack has its own natural frequency, the higher, the lower the natural frequency, when the external (the figure is provided at the bottom of the table vibration) when the frequency of the natural frequency of a shelf agreement, the most powerful swing rack , while the other two shelves almost intact.
The above three animated schematic diagram tells us that the building has its own specific natural frequency, in general, there is such a law, building more short, the higher the natural frequency, and vice versa.
Seismic waves also has its own frequency, in some earthquake, if the frequency of seismic waves is exactly consistent with the natural frequency of some of the buildings, which would exacerbate the degree of shaking the buildings, and even collapse, and nearby buildings are safe and sound.
Take Mu Bridge is located in Washington, USA Take Mu Strait, July 1, 1940 was opened to traffic before the bridge collapse, it has long been observed peculiarities of the bridge, even if only a breeze, the bridge also ups and downs powerful, so it had a nickname - galloping Gertie. Vehicles traveling on the bridge, because the bridge will be up and down, resulting in the car while visible, while invisible, while sitting in the car, just like in a roller coaster. At that time, a local sport is in windy weather to Take Mu Bridge driving or walking. Some weird man Take Mu Bridge "behavior" uneasy, but many people did not seriously.
Take Mu Bridge dancing for four months, and finally the curtain call. November 7, 1940, the day the wind speed, less than a third design wind speed limits, but still fragmented Take Mu bridge, dancing over its short life.
Take Mu collapsed bridge so that people suddenly realize that resonance great damage, so that people in the later building more consideration resonance. However, the resonance harm sometimes very subtle, a little negligence may hit.
When the January 26, 1995, China's "Long March 2 E" carrier rocket developed by the United States' Asia-Pacific Satellite No. 2 ", due to the resonance frequency of the US side did not tell the satellites, and the resonance frequency of the satellite and the rocket fairing coincidence resonance the same frequency, emission, due to the dramatic changes in wind speed and direction at high altitude, causing resonance, resulting in Xingjian explosion.
Finally, let's go back to the previously mentioned by voice shattered glass case, not to say, as long as the sound frequency consistent with the natural frequency of the glass, and for a period of time, we can guarantee the shattered glass. Not the case, to develop its "Roar power", in addition to acquired certain frequency sounds, but also trained a big voice. We usually voices around 50 decibels, and in order to put the glass shattered, the sound you get when possible emitted 100 decibels or more.
The reason is simple, even if you already know the natural frequency of a bridge is 1Hz, then you push the swing like people, 1 second to push the bridge once, then you think you can put the bridge down with it the resonance?
