You are completely correct in stating that you are not an engineer.

:)

A hollow axle is not stronger in bending than a solid axle of the same diameter and material. A hollow axle can be lighter for the same strength, but with a larger OD than a solid axle. A hollow axle can be stronger for the same weight, but with a larger OD than a solid axle. A hollow axle can be lighter and not a lot weaker than a solid axle of the same diameter. But if you take a solid axle, and drill out the center, it will be weaker.
