A concrete bean with a cross- sectional area of 32x10 sq.mm and radius of gyration of 72mm is prestressed by a parabolic cable carrying an effective force stress of 1 kN/sq.mm. The span of the beam is 8m. The cable contains 6 high tensile wires of 7mm diameter and it has an eccentricity of 50mm towards the bottom at the center of span and concentric at the supports. Adopt Ec -38 GPa and density of concrete as 24 kN/cu.mm. Neglecting all losses, estimate the deflection at the center of span (L-8m) O 5.7 mm O 35.7 mm O 25.7 mm O 15.7 mm
