A rod 40 cm long was bent along a circular arc in the form of a semiring and, using weightless knitting needles, attached to a horizontal axis passing through the center of the circle. Find the circular frequency of small vibrations of the semiring near the equilibrium position if the axis of rotation is perpendicular to its plane, g = 9.8 m/s2.
