A simply supported beam has a uniformly distributed load applied. The length of the

beam, $L=4\mathrm{.}50m,$ the base and height of the cross$-$section are $b=200\mathrm{.}0mm$ and $h=$

$400\mathrm{.}0$ mm respectively, and the intensity of the load $w=15\mathrm{.}0k\frac{N}{m}.$

Determine the absolute maximum compressive stress in the beam.

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

decimal places.
