A prestressed concrete beam with a rectangular sectin 120 mm wide by 300 mm deep supports a a live load of 3 kN/m. The spanning over 6 m is prestressed by a straight cable carrying an effective prestressing force of 200000 N located at an eccentricity of 55 mm, the density of concrete 24 kN/m3. Find : (1)- The resultant stress distribution for the centre of span cross section of the beam (2)- the presressing force which can balance the stresses due to dead load and live load at the soffit of the centre span section
