While reviewing bending of a homogeneous symmetric section, which conclusion is correct? Avoid the common trap that the neutral axis is always at the top fibre.
Choose the correct answer
the neutral axis depends only on span
the neutral axis passes through the centroid for pure bending
the neutral axis is always at the top fibre
the neutral axis coincides with the shear centre in every section
