A prestressed concrete beam is simply supported over a span of 9 m. the beam is reinforced with straight tendons situated as shown in the figure under a prestressing force of 624 kN. The beam is carrying a live load of 16.14 kN/m2 and a dead load of 24.14 kN/m² excluding its own weight, Concrete weighs 21.76 kN/m³ with modulus of elasticity Ec=21,240.55 MPa. Assuming tension concrete does not crack, what is the midspan deflection due to the given loads. (Include the sign if it is negative) 400 mm WDL (kN/m) WLL (kN/m) N.A. 150mm 600mm 50mm 150mm 650mm

Please help me ASAP. Please put the answer on the paper. Complete solution. I need the answer after 40 minutes. Rate will be given accordingly. Thank you in advance.Line AB was measured and the result is 745m. It is measured using a 30m tape that is0.005m tooshort. The tape is standardized at 20°C under a 4.5kg pull. During measurement the temperature is30°C under a pull of 9.57kg. What is the true horizontal distance of line AB due to incorrect tape length,temperature, and pull? The cross-sectional area of the tape is 0.05cm2 and E = 2x106 kg/cm2.
