8 9) With neat sketch, discuss the profile/shape of cable subjected to uniformly distributed 5
‘w’ per unit horizontal length.

b) A bridge cable is suspended from towers A and 8, 80 m apart and carries a load 30 शा 15
on the entire span. If the maximum sag is 8m at point C, calculate the maximum tension
in the cable. If the cable is supported by saddles which are stayed by wires inclined at
30 degrees to the horizontal, determine the forces acting on the towers. If the same
inclination of back stay passes over pulley, determine the forces on the towers.

9 ஐ) With neat sketches, explain the different types of arches. 6

b) A three- hinged circular arch hinged at the springing points A and B and crown point 14
C, has a span of 40 m and a central rise of 8m. It carries a uniformly distributed load

20kN/m over the left-half of the span together with a concentrated load of 100 KN at
the right quarter span point. Find the reactions at the supports, normal thrust, radial

shear and bending moment at a section D 10 m from the left support.
