SUMMARY

The tension at the midpoint of a catenary rope can be calculated using the formula T = W / (2 * cos(A)), where T represents the tension, W is the weight of the rope, and A is the angle the ends of the rope make with the horizontal. This formula is derived from the principles of static equilibrium and the geometry of catenary curves. Understanding the relationship between weight, angle, and tension is crucial for accurate calculations in engineering applications involving suspended cables.

How do I calculate the tension at the middle of a rope (weight=W) suspended at two points as a catenary? It's ends make angle A with the horizontal.
