|Why are hollow tubes stronger than full ones. Physics Forums|
A solid round bar has a “neutral axis” that when the bar is bent is not in compression or tension and so does not contribute to the resistance to bending. If the material near that neutral axis is removed and relo ed to the outside surface of the bar it becomes a tube and is less flexible than the bar of the same mass.
