A thin-walled tube with external radius of $100 \mathrm{~mm}$ and wall thickness of $2 \mathrm{~mm}$, is fixed at one end. It is subjected to a compressive force of $1 \mathrm{~N}$ acting at a point on the circumference parallel to its length. The maximum normal stress (in $\mathrm{kPa}$ ) experienced by the structure is ________________(accurate to two decimal places).
