This Demonstration treats a system consisting of three springs connecting two masses between two walls with forcing functions on the masses, given by and . The solution plots are shown and dynamically updated to reflect changes to the initial displacements and the forcing frequencies. The short-term behavior can be affected by the changes in initial displacement, but the long-term behavior is dominated by the forcing functions. The two equations being solved are:
