An axial compressive force F＝Fcr is acting on an ideal column in linear equilibrium. And then the column produces the bending deformation due to a small lateral disturbing force. If the disturbing force is removed at this time, ( ) .
A: The bending deformation will disappear and return to a straight line
B: The bending deformation is reduced and the straight line shape can not be restored
C: The bending state is not changed
D: The bending deformation continues to increase
A: The bending deformation will disappear and return to a straight line
