Harmonic oscillators may have several degrees of freedom linked to each other so the behavior of each influences that of the others. For example, two pendulum clocks (of identical frequency) mounted on a common wall will tend to synchronize. The apparent motions of the compound oscillations typically appears very complicated, but a more economic, computationally simpler and conceptually deeper description follows resolving the motion into [normal-modes].

Which eigenvectors should I ignore?
Solving an Euler-Bernoulli equation for a beam using Finite Element Method leads to the following equation
$$M \ddot{\vec d}(t)+K \vec d(t)=\vec F$$
where $M$ is system mass matrix, $K$ system stiffne …
