A homogeneous rod of mass M = 5 kg and length L = 3 m is suspended from one end to rotate around the point O in the vertical plane. From the other end, as shown in figure, the rod is attached to two identical springs with spring constants k 100 N/m (take 7 = 3,g = 10 m/s and Icm = ML). For small vibrations; F 6 What is the magnitude of the angular acceleration of the rod as function of 0? What is the period of the vibration in units of seconds? L + k fum O g k muf
