Principal Frequencies of a Double Spring-Mass System Available to Purchase

The purpose of this paper is to show how the masses of the springs will affect the principal frequencies of a double spring-mass system. The frequency equation for the system is first derived from a set of assigned boundary conditions. Then with the assumption that the mass of each spring is relatively small, a special case is considered. It is shown by approximation that the mass of the spring has the equivalent effect of changing the main mass by an amount which depends on the modes of oscillations.
