網頁Euler Buckling Theory is the classical theory presented in textbooks and classrooms. It begins simply by noting that the internal bending moment in a loaded and deformed column is −P y − P y where P P is the compressive load and y y is the column deflection. So insert −P y − P y in for M M in the beam bending equation, EI y′′ = M E ...
