Issuing this Technical Note at this time was considered appropriate as a means of reporting interim progress toward the long-range goals. The significant accomplishments are the development of a workable computer program for predicting peak accelerations and maximum displacements of the structures being considered. The implications of using the acoustical approximation are explored, and it is concluded that the procedure followed accurately predicts the peak acceleration, since in all cases of practical interest this acceleration occurs prior to the development of significant viscous drag. A result is obtained for maximum displacement of the structure, which in some cases is an upper bound but further study is indicated to determine the effect of the perturbation caused by the viscous drag.
