Abstract : Research continued on the reaction of vibrating piezoids to externally applied forces and torques, with emphasis more especially on retangular plates at present. Special attention was given to tensile stresses because of the complications introduced by the bending of thin plates under lengthwise compression. Significant data appear to have been obtained bearing upon the question as to whether force or stress is the more basic parameter. Further developments are reported in modifying the frequency equation, with a view toward making it more responsive to the utilization of information regarding the symmetry of the elements involved.
