A beam of symmetrical l-section spanning 8 m has a flange width of 150mm & flange thickness of 80 mm respectively. The overall depth of the beam is 450 mm. The thickness of the web is 80 mm. The beam is prestressed by a parabolic cable with an eccentricity of 150 mm at the center of the span & zero at the supports. The LL on the beam is 2.5 KN /m. Determine the effective force in the cable for balancing the DL & LL on the beams. Choices: 507kN, 509kN, 511kN, 505kN
