Abstract

Abstract: In this work the problem of two containers with variable mass coupled and aligned by springs is studied. The containers are filled with granular mass that lose at a constant rate. Once the containers have been emptied, the classic problem of coupled oscillators with constant mass is recovered. Analytical solutions are obtained even in the damped case where it is observed that the effect of the variable mass combines with the damping factor to produce a decay in the oscillation amplitudes. Finally, also forced coupled oscillators with variable mass problem is considered.
