Help solving the vibrating pole mystery.

In summary, an Italian newspaper reported on a street pole that has been vibrating for extended periods of time without a clear reason. Some suggested that it could be due to a nearby building site or wind turbulence, but the pole has been vibrating even when there is no wind. A video shows the pole vibrating, and some have suggested using this energy to power street lamps. Others believe it could be a case of resonance or a motor running underground. However, it may not be possible to test any hypothesis, so it is best to move on from the issue.

The online edition of an italian newspaper, reported the curious event of a street pole which seems to vibrate for prolonged times, hours, even an entire day and without any clear reason.
Someone talks about a building site in the nearby area, other talks about a wind turbulence called "vortex shredding", but the pole has been vibrating, it seems, even is absence of wind.
See the pole in the linked video:

Looks like it could be from a combination of wind and all the traffic.

The should build all street lamps like this, and harvest the energy to power the lamps.

Looks like a simple case of resonance to me. This hypothesis could be easily tested by sticking a weight to the pole and seeing is it stops.

I wonder if there could be a motor running, underground near the bottom. A water pump, for instance, at just the right frequency could be supplying the energy to make it vibrate.
I think mrpeedybob is right. Load it and see if it still resonates at a few % different frequency. One thing is sure and that is that there is no free energy getting to it.
There is probably no way of testing any hypothesis about it so we should really let it go - PF policy.
 

1. What is the "vibrating pole mystery"?

The vibrating pole mystery refers to a phenomenon where metal poles or structures exhibit a constant, low-frequency vibration without any apparent external source.

2. What causes the vibrating pole mystery?

The exact cause of the vibrating pole mystery is still unknown, but it is believed to be a combination of environmental factors such as wind, temperature changes, and electromagnetic fields.

3. Can the vibrating pole mystery be harmful?

The vibrations from the mystery are usually very low in intensity and are not harmful to human health. However, they can potentially cause structural damage to buildings or other nearby structures.

4. Is there a way to stop the vibrating pole mystery?

Unfortunately, there is currently no known way to stop the vibrating pole mystery. However, researchers are continuously studying the phenomenon to better understand its causes and potentially find a solution.

5. How does the vibrating pole mystery impact the environment?

The vibrating pole mystery does not have a significant impact on the environment itself, but it can disrupt nearby wildlife and cause stress to animals that are sensitive to vibrations.
