An $8 \mathrm{~m}$ long simply-supported elastic beam of rectangular cross-section $(100 \mathrm{~mm} \times 200$ $\mathrm{mm}$ ) is subjected to a uniformly distributed load of $10 \mathrm{kN} / \mathrm{m}$ over its entire span. The maximum principal stress (in MPa, up to two decimal places) at a point located at the extreme compression edge of a cross-section and at $2 \mathrm{~m}$ from the support is
