Exact Elastic Catenary
High-precision exact elastic catenary calculations for stayed-bridge cables, cableway ropes, and other self-weighted tension members. Use when Codex must compute unstressed length, loaded length, constant horizontal force, end tangent forces/components, chord-direction end forces/components, end tangent angles, or verify another solver's result from endpoint coordinates, axial stiffness, self weight, and either one known upper-end tangent force `TB`, one known lower-end tangent force `TA`, one known unstressed length `L0`, one known lower-end chord-direction force `NA`, or one known upper-end chord-direction force `NB`. Trigger on requests mentioning 弹性悬链线, exact elastic catenary, 无应力索长, 已知索长反求索力, 已知TA反求索力, 已知NA反求索力, 已知NB反求索力, 索力, 切线力, 弦向力, 锚固端夹角, cableway, or stayed cable when approximate parabolic methods are not acceptable.
