What is the catenary constant? The catenary constant, a, is both simple and incredibly useful. Equation 1 defines this value equal to horizontal tension, FH (force) divided by cable unit weight, w (force/length). Thus, a, has corresponding units of length. What is a catenary structure? In physics or geometry, a cable or a chain hanging […]
