An infinitely long, perfectly flexible string is subjected to a transverse force that moves with arbitrary speed. Using the method of characteristics, a solution for the string displacements is obtained. The effect of the force accelerating through a resonant speed is determined. This invariably results in large deformations if the force is concentrated. With a distributed force, the deformation can remain small if the force accelerates through the resonant speed rapidly.
