A batch of aluminium alloy yields in uniaxial tension at the stress of $330 \mathrm{MN} / \mathrm{m}^{2}$. If this material is subjected to the following state of stress: $\sigma_{\mathrm{x}}=140 \mathrm{MN} / \mathrm{m}^{2}, \sigma_{\mathrm{y}}=-70 \mathrm{MN} / \mathrm{m}^{2}, \sigma_{\mathrm{z}}=0, \tau_{\mathrm{xy}}=x \mathrm{MN} / \mathrm{m}^{2}$
$\tau_{y z}=0$ and $\tau_{z x}=0 .$ The value of $x$ that would result in yielding according to the Von Mises failure criterion is_____________ $\quad$ (in three decimal places).
