The hollow core section shown in Fig. is prestressed with four $12\mathrm{.}7mm$ diameter, $1860$MPa low$-$relaxation strands and is simply supported on masonry walls with a span length of $6m,$ center to center of the supports. In addition to its self$-$weight, the section carries a superimposed live load of $11k\frac{N}{m^2}.$ Material properties are $f_c^{\text{'}}=35$MPa and $f_{c^{\text{'}}}=25$MPa.

$($a$)$ Determine if service load stresses in the section are suitable for a Class $U$ flexural member using $18\%$ prestress loss. Flexture an a lys$,5$
