A unidirectional carbon fibre reinforced composite has the following properties: where subscript $1$ refers to the fibre direction and subscript $2$ to the transverse direction. If the $1$ direction is aligned with the global x$-$axis,

the question is: The unidirectional composite in Q$4$ is orientated at $45$ degrees to the global x$-$axis, and is subjected to a tensile stress of $7$ MPa in the x$-$axis and a compressive stress of $4$ MPa in the y$-$axis $($perpendicular to x$-$axis$).$

$*******$ Determine the strain in the x$-$axis and the strain in the y$-$axis.

where E$1=150$ Gpa, E$2=11$Gpa, G$12=10$Gpa, v$12=0\mathrm{.}3$

These are the final answer that i want you to show the steps and equations used to find them.

Strain in the x$-$axis $=3\mathrm{.}45$e$-4$

Strain in the y$-$axis $=-2\mathrm{.}05$e$-4$
