| Description |
English: In laying a cable on an irregular bottom it is of great importance that the speed should be sufficiently low. This is illustrated: suppose a a to be the surface of the sea, b c the bottom, and c c the straight line made by the cable; then, if a hill H, which is at any part steeper than the inclination of the cable, is passed over, the cable touches it at some point t before it touches the part immediately below t, and if the friction between the cable and the ground is sufficient the cable will either break or be left in a long span ready to break at some future time. |
