A suspension cable of 60 m span and of central dip of 6 m is strengthened by two-hinged stiffening girders. The dead load of stiffening girder is 20 kN /m. The girder also carries a live load of 30 kN /m over the left half of the span. The maximum tension in the cable will be nearly:
A. 2581 kN
B. 2663 kN
C. 2745 kN
D. 2827 kN
