For the circular section rod, because any diameter passing through the center of the circle is the main axis, the synthetic bending moment of the circular axis can be directly calculated when it is bent in both directions, and then the stress can be calculated according to the plane bending

Shear stresses do not only exist on vertical planes in the beam, but also on horizontal planes.
So we have zero shear stress at the outer surfaces (where bending stresses are maximum) and maximum shear stress at the neutral axis (where bending stresses are zero.
Max bending stress is 4L/h bigger than max shear stress, so shear stress unlikely to cause failure for slender beam!
