Pleas show how to get eccentriciny for this question $???$Determine the stresses at transfer and service for a simply supported post tensioned beam of span $12m$ as shown in figure $1.$ The dead load on beam excluding self$-$weight is $2k\frac{N}{m}$ and live load is $6K\frac{n}{m}$

$.$ The initial prestressing force is $1200kN$ with time dependent losses as $22$ percent. An I$-$section as shown in figure $1$ is used for the design and the structure has been designed for Class $2$ criterion. Also find the number of $12\mathrm{.}9mm$ diameter tendons $($strength $=1860\frac{N}{m}{m}^2.$ Aps $=100mm)$ required for the jacking force and if the tendons are parabolic profiled, what would be the balanced load provided by the pre$-$stressing force.
