Center of Oscillation


The center of oscillation of a compound, or physical, pendulum is a point on the line passing through the pendulum’s center of mass and perpendicular to the axis of rotation. This point is located on the same side of the axis as the center of mass, and its distance from the axis is the compound pendulum’s equivalent length l0 = I/Ml, where M is the mass of the pendulum, l is the distance of its center of mass from the axis of rotation, and I is the moment of inertia about the axis. The properties of the center of oscillation are discussed in PENDULUM.
