catenary question

[rb1957]

i'm not that familiar with catenary's (yes, i could resreach it on my own, but ...) ...

i've got a feeling that you shouldn't superimpose loadings on a catenary. the case in point has two uniform loadings applied to a catenary cable, and we're solving each independently and superimposing the results. i think this is conservative, producing higher tensions than if we applied the single resultant loading.

thoughts ?

By definition a catenary is a cable under its own weight only.

So a cable with loading applied is no longer a catenary.

Therefore it would seem to follow that the equations for a catenary no longer apply.

If you get different loads/stresses from superimposing vs not, then that means the superimposing is not working, you don't have a linear system.
