Hi Everyone, I have a question about panel vs. solid rod structures. Assume a two cubes of equal dimension and weight. Cube 1 is made of panels, ie. a hollow cube. Cube 2 is made with solid rod Material is linear elastic Which would be stiffer? I think the panel structure would be the stiffer structure because each panel is supported by another resisting bending. In the rod structure, the rod is only supported at the ends. Any input would be greatly appreciated Cheers.
