A rectangular concrete beam 278 mm wide and 471 mm deep is simply supported over a span of 11.39 m. the beam is reinforced with straight tendons situated 53 mm above the bottom of the beam under a prestressing force of 537 kN. The beam is carrying a concentrated load 87 kN at midspan, a live load of 15.36 kN/m3 and a dead load of 24.91 kN/m3 excluding its own weight. Concrete weighs 19.82 kN/m3 with modulus of elasticity Ec=20,358.51 MPa. Assuming tension concrete does not crack, what is the midspan deflection due to the given loads. (Include the sign if it is negative) Please avoid rounding off values during the course of solution proper as much as possible. Always write your answer in 4 decimal places
