Abstract

FIGUEIRA, Jalves S.. Resonance in coupled compasses. Rev. Bras. Ensino Fís. [online]. 2015, vol.37, n.1, 1302.  Epub Mar 12, 2015. ISSN 1806-1117.  http://dx.doi.org/10.1590/S1806-11173711614.

In this study, we explored the small oscillations of two coupled compasses. The pattern of oscillations and resonance frequencies of the needles is compared with the model of a system comprised by two spring-mass oscillators coupled by a spring. The measurements and analysis are performed on the basis of videos produced under controlled conditions and with the aid of Tracker video analysis software.

Keywords : resonance; harmonic oscillations; mass-spring system; coupled compasses.
