SUMMARY
The neutral axis in a composite beam does not necessarily correspond with the centroid of the transformed section. In the case of a wood beam with a steel plate fixed along the bottom, the neutral axis will be lower than that of a pure wood beam with a similar cross-section. This phenomenon is influenced by both the geometry and the stiffness of each section within the composite beam. For a deeper understanding, refer to the provided resource on neutral axis theory.
