The cable is placed on supports A and B whose elevation differs by 9 m as shown. Plot the minimum tension T0, the tension TA at support A, and the tension Tb at support B as functions of h for 1 ≤ h ≤ 10 m, where h is the sag below point A. State all three tensions for h = 2 m. The cable mass per unit length is 3 kg/m.
