A rod that has a solid circular cross$-$section with a diameter of $30$ mm is subjected to the shown loads. Determine the state of stress at point A $.$

Given:

The area moment of inertia of a solid circular cross$-$section about its neutral axis is $1_{NA}=\frac{R^4}{4}.$

The polar moment of inertia of a solid circular cross$-$section about its neutral axis is $J_{NA}=\frac{R^4}{2}.$

The centroid of a semi$-$circle is located at $4\frac{R}{3}$ from the horizontal axis representing the diameter line.

Select one:

$x=-51\mathrm{.}5$Mpa and ${}_{xz}=-1\mathrm{.}2$Mpa

ox $=57\mathrm{.}2$Mpa and ${}_{xz}=-1\mathrm{.}2$Mpa

$x=-57\mathrm{.}2$Mpa and ${}_{zz}=0\mathrm{.}4$Mpa

$x=-14\mathrm{.}6$Mpa and ${}_{xz}=-0\mathrm{.}8$Mpa

None of these
