31. He was in charge of research into the biochemistry and mechanical properties of skin. 32. It is also applied to probe the mechanical properties of a single biological cell. 33. Most silks, in particular dragline silk, have exceptional mechanical properties . 34. I stumbled on Solid as a stub while searching all articles on mechanical properties . 35. Zircaloy is chosen because of its mechanical properties and its low absorption cross section. 36. A higher fiber volume fraction typically results in better mechanical properties of the composite. 37. These curves can be used to extract more sophisticated mechanical properties of the material. 38. Cross-linked PTFE has improved high-temperature mechanical properties and radiation stability. 39. Wrought mechanical properties for extrusions are in the longitudinal direction. 40. Many natural ( or biological ) materials are complex composites with remarkable mechanical properties .
