Catenary Curve Diagram with Mathematical Equation

This image presents two simplified utility poles, positioned against a stark black background with a light-colored ground plane. The pole on the left features a visible grey transformer unit, indicating its role in an electrical distribution network. Both poles are equipped with cross arms, which are typically used to support overhead power lines. Although the lines themselves are not shown, these poles represent the foundational structures for suspended cables, whose natural sag under gravity forms a catenary curve, a key concept in civil and electrical engineering for understanding cable tension and span.
