Find the forces in the various members of the truss shown in figure. The ratio of length to the cross sectional area for all the members is the same. The frame is pinned at A and rests on roller at D.

20 kN

Attempt any two parts of the following :

(a)    A suspension bridge cable hangs between two points A and B seperated horizontally by 120 mtr. and with A is 20 mtr. above B. The lowest point in the cable is 4 mtr. below B. The cable supports a stiffening girder which is hinged vertically below A, B and the lowest point of the cable. Find the position and magnitude of the largest BM which a point load of 10 kN can induce in the girder together with the position of the load.

(b)    Define slope deflection method and explain why its use is not encouraged in the modem design offices these days; How does sinking of a prop differ from a rigid prop?

(c)    A thru Hinged Parabolic Arch of span 30 mtr. has its support at depths of 4 mtr. and 16 mtr. below crown C.
