The figure shows a thin cylindrical pressure vessel constructed by welding plates together along a line that makes an angle $\alpha=60^{\circ}$ with the horizontal. The closed vessel has a wall thickness of $10 \mathrm{~mm}$ and diameter of $2 \mathrm{~m}$. When subjected to an internal pressure of $200 \mathrm{kPa}$, the magnitude of the normal stress acting on the weld is __________ $\mathrm{MPa}$ (rounded off to $1$ decimal place).
