Revista Brasileira de Ensino de Física, São Paulo, v. 29, n. 3, p. 389-392, 2007.e- 1806-9126http://repositorio.bc.ufg.br/handle/ri/15208We show that plates having the shape of right triangles with equal hypotenuses which are free to swing about a perpendicular axis passing through the vertex of the right angle exhibit an isochronism similar to that of the simple pendulum, where the period depends on a single geometric parameter, namely the length of the string. In this case the parameter is the half-length of the hypotenuse and we show in addition that the center of oscillation is located exactly at the center of the opposite edge.porAcesso AbertoIsocronismoTriângulos retângulosPêndulo físicoIsochronismRight-angled trianglesCompound pendulumArtigo10.1590/S1806-11172007000300011
