A prestressed Concrete beam of cross section 120mm×300mm is prestressed by a straight cable carrying an effective force of 180kn at an eccentriaty of 50mm.The beam supports a live load of 3.14kn/m. Dead load is 0.869kn/m over a span of 6m. Estimate the stress at the centre of span. Stress at top fiber = 10.01 MPa Stress at bottom fiber = -0.01 MPa
