Abstract: The response of simple mechanical structures to harmonic oscillation is studied. The boundary conditions are similar to those occuring in contact problems, and they cause the oscillations to occur about a shortened length of the structure. A method analogous to that of Crozier and Hunter is used to treat the changing boundary conditions, and a first approximation that gives the magnitude of the changing boundary region is obtained.
