I have calculated the external diameter and the solid shaft is to be replaced by a hollow shaft whose internal diameter equals 60% of the external diameter, the length, material, and maximum shear stress remaining unchanged.(adsbygoogle = window.adsbygoogle || []).push({});

How can I calculate the percentage saving in weight?

What are the equations that are relative to this?

Thank u for ur help
