Recognizing the factors which contribute to potential pipeline collapse, it is now necessary to quantify the influence of each of these aspects of uncertainty: out-of-roundness, bending strain related to radius of curvature of the drilled hole, and external pressure.
Hence, the metric radius and the radius of curvature are not equal in general.
In contrast, the radius of curvature calculated for 257 layers, and especially for 2049 layers, was much less than the length of the layers, and extensive bending was predicted by this simple elastic solution.
In fact, one way to figure this mirror would be to start by making a good sphere whose radius of curvature matched the ellipsoid at some intermediate zone.
