P.6.4 In the three-pinned arch ACB shown in Fig. P.6.4 the portion AC has the shape of a parabola with its origin at C, while CB is straight. The portion AC carries a uniform horizontally distributed load of intensity 30 kN/m, while the portion CB carries a uniform horizontally distributed load of intensity 18 kN/m. Calculate the normal force, shear force and bending moment at the point D. Ans. 91-2 kN (compression), 8-9 kN, 210-0 kN m (sagging).
