Ring Impedance & String Connection: Is It Valid?

[QUOTE="berkeman, post: 6832831, member: 8921"] I agree with [USER=334404]@haruspex[/USER] that this is a complicated problem, and I'd be inclined to analyze it fully from a motion and wave equation standpoint, instead of trying to simplify it to the impedance/reflection equation. Perhaps there is a simpler way to do it, but I'm not seeing it intuitively. Also, it doesn't look like it's specified in the problem statement, but it seems clear to me that this can only work if the impedance of the 2nd string is lower than the first. The friction at the ring would seem to add impedance, so if the 2nd string had higher impedance than the first, I don't think there is any way to avoid reflections at the ring junction. I also don't understand this part of the problem statement, about the frictional force depending on the velocity. That's not normally how frictional forces work, but maybe it helps with the math somehow... [/QUOTE]
