X-Weighted - Weighted catenary - Netflix

A weighted catenary is a catenary curve, but of a special form. A “regular” catenary has the equation

y        =        a                cosh        ⁡                  (                                    x              a                                )                =                                            a                              (                                                      e                                                                  x                        a                                                                              +                                      e                                          −                                                                        x                          a                                                                                                                    )                                      2                                {\displaystyle y=a\,\cosh \left({\frac {x}{a}}\right)={\frac {a\left(e^{\frac {x}{a}}+e^{-{\frac {x}{a}}}\right)}{2}}}  

for a given value of a. A weighted catenary has the equation

y        =        b                cosh        ⁡                  (                                    x              a                                )                =                                            b                              (                                                      e                                                                  x                        a                                                                              +                                      e                                          −                                                                        x                          a                                                                                                                    )                                      2                                {\displaystyle y=b\,\cosh \left({\frac {x}{a}}\right)={\frac {b\left(e^{\frac {x}{a}}+e^{-{\frac {x}{a}}}\right)}{2}}}  

and now two constants enter: a and b.

X-Weighted - Examples - Netflix

The Gateway Arch in the American city of St. Louis (Missouri) is the most famous example of a weighted catenary. Simple suspension bridges use weighted catenaries.
