A simply supported beam has a uniformly distributed load applied. The length of the beam, $L=6\mathrm{.}00m,$ the

base and height of the cross$-$section are $b=150\mathrm{.}0mm$ and $h=300\mathrm{.}0mm$ respectively, and the intensity of

the load $w=19\mathrm{.}0k\frac{N}{m}.$

Determine the absolute maximum tensile stress in the beam.

Enter your answer as a positive value using the units of MPa $,$ to a precision of two decimal places.
