ON THE COULOMB VIBRATIONS IN THE PENDULUM MOTION %K %X In this paper, the Coulomb vibrations are discussed in order to describe the motion of the double pendulum. The pendulum`s interest is associated to mechanical clocks, the metronomes and seismometers. The linear equivalence method (LEM) formulated by Toma (1995) is applied to define the Coulomb vibration as a particular solution of the nonlinear system of equations that describes the pendulum motion. The general solutions are written as a linear superposition of Coulomb vibrations. %U http://journals.srmta.ro/index.php/rjm/article/view?path= %J Romanian Journal of Mechanics %0 Journal Article %& 65 %P 10 %V 4 %N 2 %@ 2537-5229 %8 2019-12-19 %7 2019-12-19
