Learning Goal: ${}_2=25\mathrm{.}0$ degrees from the $z$ axis in the $yz$ plane, respectively. The rectangular cross section has a height of $h=260\mathrm{.}0mm$ and a width of $w=115\mathrm{.}0mm$

Part A $-$ Free$-$body diagram of the resolved components of the moments

Part B $-$ Moments of inertia of the cross section with respect to the y$-$ and z$-$axes

To calculate the absolute maximum bending stress in the member using the flexure formula for unsymmetrical bending, the moments of inertia of the cross section must be calculated. Select the correct formulas for these values.Part C $-$ Neutral$-$axis angle due to externally applied moments

The neutral$-$axis angle of the cross section being analyzed is the axis along which there is a zero stress value. Determine the neutral$-$axis angle, $\backslash$alpha

$,$ due to the externally applied moments as measured counterclockwise from the positive z axis in the yz plane.

Express your answer to three significant figures and include the appropriate units.
