The element in the figure below:
lengthens by 0.0435mm in the x direction,
shortens by 0.0240mm in the y direction, and
contracts by 0.0026mm in the z direction,
due to the applied stresses in the x and y
directions. Determine the modulus of elasticity $E$,
shear modulus $G$, and Poisson's ratio $\nu$ for the
material. The element thickness is 25mm.
