• In this paper, the effects of the torsional moment on the free transverse vibration of circular bars are investigated with the condition that the axial elongation can be neglected. A differential equation on the non-planar motion of the bar is derived. Then the equation is solved by means of the perturbation method and the numerical one for the case in which both ends are clamped. The results show that the characteristic frequency decreases quadratically with an increase of the torsional momet, which is contrary to the case of tension. It is also confirmed that the non-planar vibration arises due to the torsional moment.
