Q. 84
A thin steel plate is loaded in the $x$-y plane as shown in the figure. Take the
Poisson's ratio of steel to be 0.3 and the modulus of elasticity of steel to be 200
$\mathrm{GPa}$. The strain along the $z$-direction is $\varepsilon_{\mathrm{zz}}=-3 \times 10^{-4}$. The value of $\sigma_{y y}$ (in
$\mathrm{MPa}$ ) is___unded off to one decimal place).
