What is the physical mechanism that limits a vibrating string fixed at both ends to producing only the harmonic series?

Answer

The string can only support vibrations where the ends remain stationary (nodes).

The physical constraint imposed by fixing the ends of the string requires the wave pattern to fit perfectly as a standing wave, meaning the ends must be nodes. This condition mathematically restricts possible frequencies to integer fractions of the total length.
