The rectangular plate is subjected to the deformation shown by the dashed line. Assume a$=750$mm$,\backslash$Delta x$=1\mathrm{.}2$mm$,$ and $\backslash$Delta y$=1\mathrm{.}5$mm$.$ Determine the shear strains $\backslash$gamma $\_($xy$)$ and $\backslash$gamma $\_($x$^(\text{'})$y$^(\text{'}))$ at point A$.$

Answers:

$\backslash$gamma $\_($xy$)=$i$,\backslash$mu rad

y$\_($x$^(\text{'})$y$^(\text{'}))=,$rad$^(2)$
