An 9m long cantilever T-beam shown supports a uniformly distributed load of 10kN/m including its own weight throughout its length. To prevent excessive deflection of the beam, itis pre-stressed with 16mm diameter strands causing a pre-stress force of 750KN. Determine the resulting stress at the top fiber of the beam at the fixed end if the center of gravity of the strands is 80mm above the neutral axis of the section. (MPa)
