The combined effects of porosity and strain rate on bone strength have been expressed by the following equation: where is the relative density. If the fracture stress of compact bone at 10 −3 s −1 is equal to 120 MPa, what is the fracture strength of cancellous bone with 50 vol.% porosity at 10 s −1?

Function: A plant cell that produces, modifies, and releases oil on the surface of a leaf.
