i need help with the analysis:

For Point A

$1.$ Using the strain gage data, determine x $,$ y and xy for each loading condition.

a$.$ Calculate x$,$ y$,$ and xy$.$

b$.$ Calculate principle stresses $1$ and $2$ as well as principle directions $($p$1,$ p$2).$

$2.$ For each of the the $40$ N loading conditions, calculate the theoretical values of x$,$ y$,$ xy $,$ $1,$ $2,$

and p$1,$ p$2.$

For Point B

$1.$ Using the strain gage data, determine x $,$ y and xy for the combined loading case only.

a$.$ Calculate x$,$ y$,$ and xy$.$

b$.$ Calculate principle stresses $1$ and $2$ as well as principle directions $($p$1,$ p$2).$

$2.$ For the $40$ N loading condition, calculate the theoretical values of x$,$ y$,$ xy $,$ $1,$ $2,$ and p$1,$ p$2.$
