A simply supported beam 6.5m long, 350mmx500mm, prestressed with a straight tendon located 150mm below the neutral axis with effective prestressing force, Pe, of 300kN. Total load carried by the beam is 20kN/m. D. Determine the compressive stress caused by the tendon alone if Pe is 150mm below the neutral axis, MPa. E. Determine the final compressive stress, MPa. F. Determine the final tensile stress, MPa.
