Extracted text: A suspension cable 150 m span and 15 m central dip carries a load of 2 kN/m. Calculate maximum and minimum tension in the cable, horizontal and vertical forces in each pier under the following conditions: (i) Cable passes over a frictionless rollers on top of the piers. (ii) Cable is firmly clamped to saddles carried on frictionless rollers on top of the piers. For both the cases the back stay is inclined at 30° with the horizontal.
