The period of oscillation of the rod is T = 2.20 seconds and the pivot point is located at a distance d= L/4 meters, where L is the unknown length of the rod. Find the length L of the rod if the Moment of Inertia of the rod is I = 0.15 ML² (kg•m²), where M is the mass of the rod and L is the unknown length of the rod.
