What is the recommended catenary angle when loaded, under optimal conditions?

The recommended catenary angle when loaded, under optimal conditions, is 20 degrees because this angle provides a balance between tension and sag in the supporting structure. At 20 degrees, the catenary curve, which represents the shape a hanging cable takes under its own weight, remains efficient, allowing for effective load distribution and minimizing excessive stress on the system.

A catenary angle that is too shallow could lead to increased sag and an uneven distribution of weight, potentially compromising the integrity of the structure. On the other hand, a steeper angle may introduce unnecessary tension, making the structure more prone to failure or mechanical issues. Therefore, 20 degrees is often cited as an optimal angle, resulting in both safety and performance efficiency for catenary systems under typical loading scenarios.
