Figure 5.1 shows the mathematical model of a cable which is supported at two
points (A and B) at the same elevation. The relationship of the x- and y-
coordinates of a point on the cable, s(x, y), and the length of the cable segment,
Is (C is the middle point of the cable) is given by Equations 1 and 2. It is known
that the distance between A and B (D) is 15 m and the distance of C to the x-
axis (c) is 5 m. Calculate the sag of the cable, h.
