Poorly described, but I take it to mean that the pressure on the cables themselves from the water would cause them to be destroyed.

- kragen 17y agoI don't see how. Accelerated rusting? Transition to a different crystal structure?
- ram1024 17y agoyou can make something buoyant, but it still has mass, and if you try and move that mass you're going to have to exert force, which will snap the cable. hope that helps
- jonah 17y agoCrushing?
- ars 17y agoCrushing on an atomic level? There is no void (air) inside the cable, and the pressure is even all the way around - the only crushing you can do is move the atoms closer to each other. (Compress actually, not crush, and iron is basically incompressible.)
- kragen 17y ago"moving the atoms closer to each other" is what I was talking about; under some circumstances, that could manifest as a shift to a different crystalline structure. (If you search for information on high-pressure crystalline phases of materials, you'll find a lot of interesting things.) "Iron is incompressible" is often a useful approximation, but no material is actually incompressible (that would entail, among other things, faster-than-light propagation of shock waves and infinite hardness) and many day-to-day materials are less compressible than iron. Glass, for instance. Most metal objects do actually have voids in them, but you can manufacture metal objects that don't, and it's not clear that having voids in your cable would cause it to be damaged by pressure.
