Strength - Benefits of composite s composite s Lab
When it comes to strength there are four primary kinds that affect structural design: specific tensile shear and compressive strength. Specific Strength. A material’s strength-to-weight ratio – also called its specific strength – is a comparison of its strength in relation to how much it weighs.

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.
