Since this cannot be the case, the force will be resolved into two components, one of which will cause a tensile stress in the rod and the other will pass through the centroid of the compressive stress area.

Above the centroid of compression there is nothing but a trifling amount of embedment of the stirrup.

The couple is equal to the moment of the applied load W about an axis drawn through the centroid of the section p at right angles to the plane of bending.

Let l be the length of the beam, x the distance of the section p from the fixed end A, y the distance of any point below the horizontal plane through the centroid of the section at A, then the bending moment at p is W(l - x), and the longitudinal tension P or X_x at any point on the cross-section is - W(l - x)y/I, and this is related to the bending moment exactly as in the simpler problem.

The shearing strain corresponding to U is a distortion which has the effect that the straight vertical filaments become curved lines which cut the longitudinal filaments obliquely, and thus the cross-sections do not remain plane, but become curved surfaces, and the tangent plane to any one of these surfaces at the centroid cuts the central line obliquely (fig.
