Forward) that the optimum structure for a space elevator cable (going from a full 1G to microgravity) would be that of a semi-exponentially decreasing cone section. This turns out to be equivalent to a greatly reduced breaking length (calculated at constant section). Now, I (half) remember this being around 6000 km for Earth. In the case of the Ringworld, the constant section case applies. | |
