Keywords:over-damped symmetrical system ,transient response,forth order non-linear differential equation,eigen values,
A fourth order nonlinear differention equation modeling an over-damped symmetrical system is considered. A perturbation technique is developed in this artical for obtaining the transient responsewhen the eigenvalues are in integral multiple. The results obtained by the presented technique agree with those results obtained by the numerical method nicely. An example is solved to illustrated method.
