Расчетное значение критической потери устойчивости при изгибе сжатого стержня вдоль главной оси, FcEx.

Critical Buckling Design Value for Compression Member in Major Axis, F_cEx

F_{cEx} = F_{cE 1} = \frac{0.822 \cdot E_{\min}'}{{[\frac{l_{e 1}}{d_{1}}]}^{2}}

F_{cEx} = F_{cE 1} = \frac{0.822 \cdot 510, 000 psi}{{[\frac{36.0 in}{3.5 in}]}^{2}}

F_{cEx} = F_{cE 1} = 3, 963 psi

F_cEx	Critical buckling design value for the compression member in the major axis, psi
E_min'	= E_min ⋅ C_M ⋅ C_T ⋅ C_i = 510,000 psi
l_e1	Effective length = 36.0 in
d₁	Member depth = 3.5 in
