A suspension cable 140 m span and 14 m central dip carries a load of 1 kN/m. Calculate the maximum and minimum tension in the cable. Find the horizontal and vertical forces in each pier under the following conditions: (a) If the cable passes over a frictionless rollers on top of the piers (b) If the cable is firmly clamped to saddles carried on frictionless rollers on top of the piers.
