Neutral axis in a composite beam
Does it correspond with the centroid of the transformed section? For example, if a wood beam had a steel plate fixed along the bottom, would the neutral axis be lower than that of a pure wood beam of similar cross section?
Any links showing example probs would be nice too. Sorry that this is a little more S.E. type of question.

No. It will be a function of both the geometry and stiffness of each section.
Scroll down to the section about neutral axis and all will become clear.
