| Abstract: | The differential equation of the supported beam under axial force are derived.The effect of the axial force on the frequency of the supported beam under different torsional spring is discussed,and the analytical expression of critical axial force of the supported beam is also obtained using the given eigenfunction.The effect of torsional spring on the values of critical axial force is discussed according to the analytical expressions derived. |
