A 6 m long cantilever beam 250 mm wide x 600 mm deep, supports a uniformly distributed dead load (including beam weight) of 5KN/m throughout its length and a concentrated live load of 8 KN at the end of the beam, it is pretensioned with 12 mm diameter strand causing a final prestress of 540 KN. Determine the eccentricity of the prestress force at the fiber end such that the resulting stress at the top fiber of the beam at the fixed end is zero at transfer.
