dc.descriptionAbstract: The elementary theory of coupling or resonance between a moving load and the flexural waves generated by it in a floating ice sheet is developed and verified by experiments. The theory indicates that for shallow water the critical velocity is approximately 20 percent greater than the velocity of long water waves. Experiments were carried out, using one and two vehicles as moving loads on ice sheets one to two feet thick. At the critical speed (for a single vehicle) the maximum observed motion approximately 2.5 times the static deflection. For two vehicles, running in tandem a half wave length apart, a considerable cancellation was observed. Attempts to solve the problem of a semi-infinite plate on an elastic foundation with a free edge under concentrated load (the ice-breaker problem) are reported. No satisfactory solution was obtained.-
