A cable of length L 1 D is suspended between two points that areat the same elevation and a distance L apart. (a) Assuming that D issmall compared to L and that the cable is parabolic, determine theapproximate sag in terms of L and D. (b) If L 5 100 ft and D 5 4 ft,determine the approximate sag. [Hint: Use only the first two termsof Eq. (7.10).]
