• curprev 20:2520:25, 21 May 2024 Engeer talk contribs 52,279 bytes +37 →Variational formulation: Missed these in the 21:11, 17 May 2024‎ edits (changing λg to w), because of the shift in notation (in this section ρ was used instead of λ to indicate mass density, to avoid confusion with the use of λ as a Lagrange multiplier). undo
• curprev 20:1920:19, 21 May 2024 Engeer talk contribs m 52,242 bytes +4 →Catenary bridges: Change two references to mass to read "weight". While, under the uniform gravitational field assumption, "mass" is equally accurate, the important thing about catenary analysis is force (weight) not inertia (mass). undo

• curprev 21:1121:11, 17 May 2024 Engeer talk contribs 52,468 bytes −303 (passim): Replace λg (lineic mass density times gravitational field strength) by w (lineic weight density) throughout, as the catenary depends only on the force (weight) acting on the cable, not the inertial mass independent of g. undo

• curprev 21:2721:27, 15 May 2024 Engeer talk contribs 52,713 bytes −1,633 Reverting: 1) subsequent edits clusily clobbered my carefully considered edits; 2) the new "second alternate derivation" is a long-winded rehash (*not* a "simpler version") of the primary derivation. If the primary derivation is considered deficient, let's discuss in the Talk section. undo Tag: Manual revert

Part of this is due to an incomplete revert of the 26 Feb 2024 edits, but mainly the (true) conclusion does not directly follow from the offered premises. I will add a "Tension" section which does this right. undo

• curprev 21:3921:39, 17 April 2024 Engeer talk contribs 51,226 bytes +1 I found the previous version of the derivation of the catenary equation to be unsatisfying. It made a detour into deriving y = g(s) and mentioning its relation to the tension T; while these are of potential interest in other contexts, they are a distraction from deriving of y = f(x). Furthermore, the derivation concludes in a hand-wavy "these results can be used to eliminate s" step to get to the desired result. I think my changes result in a cleaner and clearer presentation. undo
