Lateral vibrations of twisted rods
propeller blade, in the unloaded state. The bending vibrations of such a rod have been dealt with by H. Reissner,1 who derived the differential equations under most general assumptions, without, however, to the best of our knowledge, proceeding to their solution. Subsequently, a number of authors have treated particular cases by approximate or experimental methods.2 In view of the possibilities offered by modern computers, the problem actually is ripe for rigorous treatment. It is solved in this paper for an isotropic,
