This problem requires more analysis as both the loading and cross-sectional shape are unsymmetric. The procedure is similar to the previous example. First need to find the centroid, moments of inertia about the x and y axes, and the product of inertia.
The centroid is at
and the moments of inertia and product of inertia are
The components of the applied bending moment are determined as
The x component is negative because it causes tension in the first quadrant.
(a) Since this is a homogeneous section, and it is assumed to be within its elastic limits, the neutral axis will pass through the centroid. Its angle with respect to the x axis is
(b) The maximum bending stress occurs at the farthest point from the NA, either at point A or B.
Therefore, point B is the location of maximum bending stress.
