Abstract
The elements of longitudinal and shear waves in solids are reviewed and applied to the propagation of sound in an I beam. Comparison with experimental data reveals that principle modes of vibration in an I beam excited under a number of different source placements seem to be dominated by the first flexural mode. A variety of source transducers were constructed for the efficient excitation of motion in the beams.
