- According to Euler's column theory, the crippling load of a column is given by [img=128x27]18032d66b024c7f.png[/img]. In this equation, the value of μ for a column with both ends hinged, is ( ) A: 0.25 B: 0.5 C: 1.0 D: 2.0
- The cross-sectional area of each column is the same. Under the same conditions, the stability of the column is the best when the column adopts the cross-sectional shape shown in fig. （ ）.[img=549x158]1803a2588a00e24.jpg[/img] A: （a） B: （b） C: （c） D: （d）
