Buckling euler equation
WebEuler Column Buckling: Non-uniqueness of deformed configuration moment/curvature: ode for buckled shape: free body diagram (note: evaluated in deformed configuration): Note: … The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). This ratio affords a means of classifying columns and their failure mode. The slenderness ratio is important for design considerations. All the following are approximate values used for convenience.
