1. You have two-cylinder made from the same material. They are made to have the same diameter and length. The only difference is that one is solid and the other one is hollow. Which one has higher stiffness when bending? 2. Again you have two-cylinder but now these two-cylinder rods have the same mass and length, which one has higher stiffness? 3. Taking the two-cylinders with the same mass, which one has higher resonance frequency when you impact the end of the rod?
