Before revision: For example, in a beam in the figure, the bending moment vector due to stresses in the cross-section A perpendicular to the x-axis is given by Expanding this expression we have, We define the bending moment components as The internal moments are computed about an origin that is at the neutral axis of the beam or plate and the integration is through the thickness () Example 300px| Computing the bending moment in a beam .
