Stabilizing Force

F_{c} = C * w = \frac{2 * P}{L} * \frac{w_{0}}{1 - \frac{P}{P_{e}}}

F_c	Lateral stabilizing force
C	Spring stiffness of the lateral support
w	Lateral deflection of the buckling member in the center
P	Compression axial force in the buckling member
L	Span between the support and the support spring
w₀	Pre-deformation from precamber due to geometric imperfection
P_e	Critical load of the buckling member
