11. Draw the influence line diagram for shear force and bending moment for a section at 5 m from the left hand support of a simply supported beam, 20 m long. Hence calculate the maximum bending moment and shear force at the section, due to an uniformly distributed rolling load of length 8 m and intensity 10 kN/m run.
Or
A simply supported beam has a span of 15m. UDL of 40kN/m and 5m long crosses the girder from left to right. Draw the influence line diagram for shear force and bending moment at a section 6m from the left end. Use these diagrams to calculate the maximum shear force and bending moment at this section.
12. Find the influence line diagram for reaction B in a continuous beam ABC of span AB 6m and BC 5m. Support A is hinged and support B and C is roller. Take EI as constant throughout.
Or
Make neat diagrams of the influence lines for shearing force and bending moment at a section 3 m from one end of a simply supported beam, 12 m long. Use the diagrams to calculate the maximum shearing force and the maximum bending moment at this section due to a uniformly distributed rolling load, 5 m long of 2 kN per meter intensity. Use Muller-Breslau's principle.
13. A three hinged circular arch of span 16 m and rise 4 m is subjected to two point loads of 100 kN and 80 kN at the left and right quarter span points respectively. Find the reactions at the supports. Find also the bending moment, radial shear and normal thrust at 6m from the left support.
Or
A symmetrical three hinged parabolic arch of span 40m and rise 8m carries an udl of 30kN/m over the left half of the span. Calculate the reactions at the supports and also bending moment, radial shear and normal thrust at a distance of 10m from the left support.

14. A suspension cable of 130 m horizontal span is supported at the same level. It is subjected to a uniformly distributed load of 28.5 kN per horizontal metre. If the maximum tension in the cable is limited to 5000 kN, calculate the minimum central dip needed.
Or
Explain the analysis procedure for a space truss using tension coefficient method.
15. A two span continuous beam ABC has span lengths AB 6 m and BC 6 m and carries a uniformly distributed load of 30 kN/m completely covering the spans AB and BC. A and C are simple supports. If the load factor is 1.80 and the shape factor is 1.15 for the section, find the section modulus needed. Assume yield stress for the material as 250 N/mm2.
Or
Analyze the propped cantilever beam is carrying UDL of w/m over the entire span length of L. Also determine the collapse load, if plastic moment is Mp.
