Purpose: Illustrate a system with two pendular modes of oscillation.
Description: A ball is suspended by a string attached to another string which hangs from a support rod as shown in the photograph. In one direction the pendulum swings with a short length while in the orthogonal direction it swings with a much longer length. When the ball is moved in any other direction and released the resulting motion is a combination of these two orthogonal modes.
