A rectangular concrete beam 260 mm wide and 381 mm deep is simply supported over a span of 11.57 m. the beam is reinforced with straight tendons situated 58 mm above the bottom of the beam under a prestressing force of 626 kN. The beam is carrying a concentrated load 66 kN at midspan, a live load of 18.47 kN/m3 and a dead load of 20.23 kN/m3 excluding its own weight. Concrete weighs 22.70 kN/m3 with modulus of elasticity Ec=19,468.26 MPa. Assuming tension concrete does not crack, what is the midspan deflection due to the given loads. (Include the sign if it is negative)
