in cable x y s 1 Many problems involving catenary cables can be solved using the following formulas: s = c sinh (x/c) (1) y 2 s2 = c 2 (2) W = ws (3) y = c cosh (x/c) (4) T o = wc (5) T = wy (6) where w = weight of cable per unit length of cable, and W = weight of length of cable from low point to a point a distance s along the cable.
h = cable sag (ft, m) mass and weight ; The vertical support forces at the end of the cable can be calculated as. R 1y = R 2y = R y = q L / 2 (2) where . R 1y = R 2y = R y = vertical support forces (lb, N) The resultant forces acting in the support ends - and in the direction of the cable close to the supports - can be calculated as
