A prestressed concrete beam of section 120 mm x 300 mm is used over an effective span of 6000 mm to support a uniformly distributed load of 4 kN/m including the self- weight of the beam. The beam is prestressed by a straight cable carrying a force of 180 kN located at an eccentricity of 50 mm. What is the stress due to prestressing force?
