    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.

    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.

    just in case anyone is still under the impression, the Tacoma bridge did not fall because of resonance. it fell because of aeroelastic flutter.

    • @lindsaywells501
      @lindsaywells501 5 ปีที่แล้ว +2

      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?

    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?

    Καθηγητά πως μπορούμε να τοποθετούμε σε κάποια κατασκευή, ενα δείγμα απο καθε υλικό και να εισπράττουμε την αντιστοιχία του σε ακουστική συχνότητα;
    θα με βοηθούσατε παρα πολυ στον πείραμα μου αυτό, αν είχατε τον χρόνο να ανταποκριθείτε.
    ευχαριστώ πολυ.

    Just like a bridge can have resonance and waves, an o neil cylinder would also have to contend with that.

      @@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
