Please solve both $10-2$ and $10-3$ in DETAIL. $10-2$ I partially undersatnd but $10-3$ is confusing me$.$ Please help.

$10-2.$ The state of strain at the point on the pin leaf has components of

$lo{n}_x=200({10}^{-6}),lo{n}_y=180({10}^{-6}),$ and ${}_{xy}=-300({10}^{-6}).$ Use the strain

transformation equations and determine the equivalent in$-$plane strains on an

element oriented at an angle of $=30$ counterclockwise from the original

position. Sketch the deformed element due to these strains within the $x-y$ plane.

$10-3.$ Solve Prob. $10-3$ for an element oriented $30$ clockwise.
