Thus the second moment of area will vary approximately as the inverse of the cube of the density, and performance of the beam will depend on Young's modulus divided by density cubed. However, caution must be exercised in using this metric. Thin-walled beams are ultimately limited by local buckling and lateral-torsional buckling. These buckling ...
O-F122 in turn is divided into O-MF38 (TMRCA 4,680 years, currently distributed mainly in northern China and accounting for the Y-DNA of approximately 0.02% of the total male population of China) and O-F114 (TMRCA 15,320 years, accounts for the Y-DNA of approximately 11.29% of the total male population of China).
