7 68 A thin rod of length L area of cross section S is pivoted at its lowest point P inside a stationary homogeneous non viscous liquid Figure 7 126 The rod is free to rotate in a vertical plane about a horizontal axis passing through P The density d of the material of the rod is smaller than the density d of the liquid The rod is displaced by a small angle 0 from its equilibrium position and then released Show that the motion of the rod is simple harmonic and determine its angular frequency in terms of the given parameters Fard 71 2 d d Figure 7 126
