Finally I see the experiment done by a pro who can think about it better for us. Cus he is a truth seeker or I have Faith that he is. This is amazing!!! It feels like watching science fiction.
Daniel, you are absolutely right. It was flutter. It was was self-excited vibration caused by vortex shedding because the bridge roadway was a bluff body.
Is there a lecture or video that explains WHY resonance does that? With formulas and all. I saw this explanation once, and if I remember correctly, there is a division by zero somewhere in there. Which, of course, produces infinity.
The amplitude at resonance of an undamped system is infinite. This is seen in the mathematics. But all systems have damping of some degree, however slight. A lightly damped system at resonance will hit its mechanical stops at the resonant frequency and tear itself apart.
do force quantity have anythings to do with vibrating frequency of the objects? suppose i hit the object with 10 N force and later on with 50 N force, what will be the difference in frequency of vibration of the objects?
@@beeagle5801 the frequency required to break the glass is about 556 hertz which can be produced through sound waves easily because it ranges only from 20 to 20000 hertz but the frequency of the electromagnetic spectrum ranges from 10^10 to 10^24 hertz which is very high from what frequency we actually need to break the glass and since the light waves can't have the frequency anywhere near 500 hertz it's not possible for the light waves to match the frequency of the particle's oscillating motion in the glass
What was being used to produce the sound? What kind of "plate" was next to the glass? What was the plate attached to thate lowered and raised the volume and frequency?

Resonance. You leave me in a world of infinite questions.
Imagine what tesla's brain felt like lol
Tht was amazing it was like the matter of glass is expanding
Does anyone know where this particular movie on Tacoma Narrows Bridge shown by Walter can be found? I cannot find it on youtube...
just in case anyone is still under the impression, the Tacoma bridge did not fall because of resonance. it fell because of aeroelastic flutter.
daniel I thought it was due to wind resonance
Greeces public school still say it did
Can you tell me how can we reduce the effect of resonance in different materials?
Daniel, you are absolutely right. It was flutter. It was was self-excited vibration caused by vortex shedding because the bridge roadway was a bluff body.
Isn't aeroelastic flutter an example of resonance?
I would definitely fail his lesson :d
The strobe wasn't a strobe at all, it was just a light flashing on and off annoyingly. It went at about 2 Hz instead of 440Hz.
Isnt that what a strobe does?
Interesting! Never knew Benjamin Horne teached science classes.
He is walter lewin
I am very happy with your experiment sir. I'm from India my name is Vinod iam also physics lecturer
Can you tell me how can we reduce the effect of resonance in different materials

Just like a bridge can have resonance and waves, an o neil cylinder would also have to contend with that.
Is there a lecture or video that explains WHY resonance does that? With formulas and all. I saw this explanation once, and if I remember correctly, there is a division by zero somewhere in there. Which, of course, produces infinity.
Kurtlane Yes.

good lesson

Depends on it structure and shape.
Please use a link to walter lewin's course on youtube as opposed to copying and redistributing content
To all who are about to watch this video, do not, I repeat, DO NOT watch this video in your kitchen. DONT DO IT, its no fun
How did you know 😂😂😮
I want to meet you sir how
Thank you very much sir
great
"then he talked about the significance." " It will be significant."
thanks
why not go back to 1908 and Tesla's Tunguska explosion?
I hope those cars on the bridge were insured
Is glass can be broken by frequency of light just like frequency of sound??
Light waves and sound waves are two different things
@@spockmx9426 yeah they are different . But they r waves thus have frequency.
But what kind of difference make them different .
@@beeagle5801 the frequency required to break the glass is about 556 hertz which can be produced through sound waves easily because it ranges only from 20 to 20000 hertz but the frequency of the electromagnetic spectrum ranges from 10^10 to 10^24 hertz which is very high from what frequency we actually need to break the glass and since the light waves can't have the frequency anywhere near 500 hertz it's not possible for the light waves to match the frequency of the particle's oscillating motion in the glass
@@spockmx9426 that's the satisfying answer👍🙃
That was cool👍
What was being used to produce the sound? What kind of "plate" was next to the glass? What was the plate attached to thate lowered and raised the volume and frequency?
It is simply a speaker with a diffuser, which is driven by a signal generator.
