I understand that Q is zero about the neutral axis, and that this is, in fact, how the neutral axis is defined. The first moment of area above the neutral axis is Q, and that below the neutral axis is -Q.

However, I've also read that the maximum value of Q occurs at the neutral axis. What I don't understand is how this is compatible with the fact that Q is 0 about the neutral axis.

It would be great if somebody could clarify. Thanks in advance.
