A certain cable, 504.76 ft long is suspended between two supports at the same elevation and 500 ft apart, the load is 500 lbs per horizontal foot including the weight of the cable. Calculate the sag of this cable using Newton-Raphson method up to 5 iterations with initial guess of d (sag) 10 ft. Use parabolic equation. Parabolic Equation: 8d? 32d4 s = L+ 3L 5L3 Where: S length of the cable L distance between two supports
