A prestressed concrete beam has a cross section $B=386mm$ and $H=862$ mm $,$ spans $L=6m$ and has tendons located $h=139mm$ from the bottom of the beam. The characteristic compressive strength of the concrete is $40\frac{N}{m}{m}^2.$

Its tendons have a characteristic strength of $F=1,105kN$ and initial prestress losses are $27\%.$

At TRANSFER, what is the maximum bending tensile stress induced in the beam due to its self weight $($Sigma Mswt$)?$

Give your answer in N$/$mm$^2$ to two decimal places and do not include units in your answer. Do not include $+/-$ signs in your answer.
