Double compound pendulum (Each)

This apparatus provides a dramatic demonstration of physical pendulum
behaviour. For small amplitudes of oscillation the pendulum exhibits
predictable behaviour; however, for large amplitudes the motion is chaotic.
Students will be amazed at the apparent random oscillation and that the motion
is different every time. In addition the apparatus may be locked in two
positions giving two different length physical pendula. The variation in
period between the physical pendulum and an approximated simple pendulum can
be demonstrated. From the given data of mass distribution the centre of
oscillation may be determined and therefore a value for g may be found.
