Stiffness helps reduce buckling loads.adamjgs 3y agoThe buckling load is the load at which a structure buckles. I think you mean that stiffness helps resist buckling.ummonk 3y agoErr yeah I mean that stiffness reduces the internal stress caused by external compression force. Stiffness increases the buckling load of a material.
