Centre Of Oscillation is that point in a body suspended from a point and made to vibrate, in which all its force is collected, and to which point, if an obstacle were applied, all its motion would cease. To find the centre of oscillation in a compound pendulum: - Multiply all the parts or bodies of which the pendulum is composed, each by the square of its distance from the point of suspension, and divide the sum of the products by the product of the whole weight of the pendulum, multiplied by the distance of the centre of gravity from the point of suspension.
