Solving a problem in physics, section 62, point 51 wave

51. A homogeneous rod of length L = 40 cm, mounted perpendicular to the horizontal axis, performs small oscillations under the influence of gravity. To determine at what distance l from the center of mass to the axis of suspension of the oscillation frequency of the maximum if the friction forces can be neglected.
