Did you measure the distance between the poles? I suspect it’s different from all the other spans, so this one happens to have a resonant frequency that exactly matches whatever vibration source is already there (could be the tension too). As for sources of vibration, wind is probably it, even if it’s not strong. If it just happens to create the right frequency, the cable will vibrate just like a violin string.
I immediately thought of the original Tacoma Narrows Bridge, which collapsed after wind caused a resonance to build up and literally shook itself apart: en.wikipedia.org/…/Tacoma_Narrows_Bridge_(1940)
No, I’ve never tried to quantify the variables in that way. Just out walking the dog, and notice this strange behavior from time to time. I always assumed the poles were placed a specific distance apart, but honestly, I’m not sure. I suppose if I ever have the urge to pace it out to get a good estimate, I will…
This is indeed very interesting. I can reccomend asking the telecom company that owns the line with a quick email as to whats going on here, they usually like to answer such questions. Maybe post in a sub thats more familiar with mechanics/electronics or even general asklemmy?
Probably some combination of electromagnetic effects in that specific section. Happens to oscillate just right. Though these weights can be used for wind issues, I’m seeing a lot of references to dampening other kinds of vibrations. Might help you find a better answer.
Hmm. It’s odd that this isn’t ALWAYS vibrating, but it IS only between these two poles that I’ve noticed the vibration. But why not between other sets of poles? And since the cable vibrating the most isn’t a power cable (I believe it’s fiber, but it could be copper - but it’s definitely telecom, since it’s not insulated on the top crossbar, as the other power cables are), it can’t really be much power going through it. I’m kind of hoping someone else has seen similar behavior somewhere else. You can see the anti-wind-twist devices (don’t know what else to call them) bolted to the other telecom cable (sort of diamond-shaped) and they will cause the cable to stabilize when the wind is really blowing, but you can see the wind isn’t blowing at all, and the cable continues to vibrate quite noticeably. I really do hope someone else has seen something like it elsewhere…
In regards to it only being between those two poles, I’d wager it simply comes down to tension. The other cables are tensioned correctly and this section is either too loose or intentionally loose as some sort of expansion/contraction relief.
I was wondering if Judge Reinhold and that guy with the mustache would be in it… and there they were at the very end. I might actually give this one a chance!
Hello, my name is Hollywood. It has come to my attention you at one point liked this thing. For your entertainment I have shit all over this thing and would request you consume it.
No thank you?
Shoves shit down your throat - I SAID FOR YOUR ENTERTAINMENT!
You mean Murphy or the studios? I can’t fault Murphy for taking a paycheque, but if the studios think this is going to make money then they’re likely in for a rude awakening.
For me, I subscribe to Deezer (or you can do a trial) and run Deemix which is able to download the music in MP3 or FLAC. It directly downloads the music using Deezer’s API.
As far as organizing it goes, I typically just host it with Plex or a Subsonic player like Navidrome.
