Coupled pendulum without attaching springs

[Monr1pper]

Homework Statement

I conducted an EEI on coupled pendulums without the springs,
thinking that it would be a basic experiment.
Yet when the length of the pendulum and the distance apart was equal, the pendulums oscillated for more then 30 mins while the others with different length only last around 40 secs
the length of the string and distance between the two was 37cm

was just wondering if any new any sites on coupled pendulums without springs
or why this happened??

thanx all the help would be much appreciated

Homework Equations N/A The Attempt at a SolutionThis is a phenomenon known as synchronous motion. This occurs when two pendulums of equal length and distance apart are released from the same initial angle. The two pendulums will eventually synchronize and move together. The synchronization is due to the energy transfer between the two pendulums. As one pendulum swings, it transfers energy to the other pendulum, which causes it to swing in the same motion. This energy transfer creates a feedback loop with both pendulums sharing the same oscillating motion. This phenomenon is often used in clocks to make them keep accurate time.
