Coupled pendulum without attaching springs

  1. Jun 23, 2010 #1
    1. The problem statement, all variables and given/known data
    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 with out springs
    or why this happened??

    thanx all the help would be much appreciated
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
