Loaded Catenary

[TomGutman]

The attached file provides the solution for a cable supporting its own weight plus a point load at an arbitrary point on the cable. Each segment (one side of the point load) is a segment of a catenary. If the weight of the load is zero the entire cable hangs as a single catenary. Provision is made for the cable to stretch (elastically, proportional to the tension in the cable) and for the attachment points to move horizontally as a linear response to a horizontal force.

I realise this is from a long time ago, but I tried to convert the .mcd file to a .mcdx file using the latest version of MathCad, and it gave several errors and warnings and only converted half the file! Any chance you could generate a .mcdx file, or even a PDF file that I could read? Thanks! Ian Viney

Please find the PDF file (and Mathcad Prime worksheet) in the attachment.

Now (Mathcad Prime vs old Mathcad) we can use units in calculations. 

See please the chapter 7 here
