The Bravais Pendulum: The Distinct Charm of an Almost Forgotten Experiment
Babovic, V. M.; Mekic, S.
European Journal of Physics, v32 n4 p1077-1086 Jul 2011
In the year 1851 in Paris, the apparent change of the plane of oscillation of a linear pendulum was observed by Leon Foucault. In the same year, at the same place, the unequal duration of the oscillations of a right- and left-handed conical pendulum was observed by Bravais. Today, the Foucault pendula are common at universities, the Bravais pendula not at all. We have revisited and experimentally tested Bravais's method and found it worthy of revitalization in student labs. (Contains 3 footnotes and 6 figures.)
