A rectangular conerete beam 250 mm wide and 375 mm deep, is used to support a live load of 4.25 KN/m,and dead load of own weight over a span of 8 m The beam is prestressed with straight cable having eccentric of 65 mm below the centroid axis at the center of beam. Calculate the required minimum pre-stressing force at the service load stage? Take unit weight of concrete equal to 24kN/m'.
