Total Energy in a Rigidly Terminated String
The total energy in a length , rigidly terminated, freely
vibrating string can be computed as
(C.54) | |||
(C.55) |
for any . Since the energy never decays, and are also arbitrary. Thus, because free vibrations of a doubly terminated string must be periodic in time, the total energy equals the integral of power over any period at any point along the string.
