The paper deals with the construction of the equation of motion of a section of a one-dimensional linear continuum in the state of spatial combined bending-rotational oscillation. The basic decomposition of the general spatial motion of a rigid body in the center of gravity is used to define the state of the continuum element. General spatial motion is replaced by displacement and relative spherical motion. The transverse oscillation of the continuum in the field of centrifugal forces mediates the dependence of the angular velocity on the rotation of the system.
