This is a two part question. In the first part you are asked to determine the mam moment that can be applied to the beam if it is bent about the z axis. They then ask you to redo the question bending about the y axis. This is probably a really simple question but what is the difference in bending about different axis? I understand what I need to do in order to solve teh question I'm just having trouble visually picturing and understanding what the difference is when you bend it about the y axis and when you bend it about the z axis. I've posted the solutions that were provided to me by my prof. In this question I'm unsure why it is they use the parallel axis theorem to calculate the moments of inertia of pieces 1 and 3.

Sorry if this is posted in the wrong place.
