$2$b$.$ Ap orthotropic, transversely isotropic material is subjectod to a lwo dimensiocal seress condition along the principal material ares $1\mathrm{.}23$ as shown in Figure $2$ and the enginecring constants for the material are as follows:

Determine all strains associated with the $123$ ares. Use appropriate symmeny conticioa and the ratrix in Equation $1$ for the solution $(15$ points$).$
