Question:

Two strain gages $a$ and $b$ are attached to the surface of the plate made from a material having a modulus of elasticity of $E=70 \mathrm{GPa}$ and Poisson's ratio $u=0.35$. If the gages give a reading of $\epsilon_{a}=450\left(10^{-6}\right)$ and $\epsilon_{b}=100\left(10^{-6}\right)$, determine the intensities of the uniform distributed load $w_{x}$ and $w_{y}$ acting on the plate. The thickness of the plate is $25 \mathrm{~mm}$.
