The researchers studied how a gear system behaves when there is some space between the gears. They found a way to calculate a special number called the Lyapunov exponent, which helps determine if the gear system moves in a regular or chaotic way. The results showed that the Lyapunov exponent is a useful tool for understanding the dynamic behavior of gear systems.
