Abstract
This paper discusses by energy Theorem the method of approximate compulation for the lowest eigenfrequcncies of rectangular plates, on which there are symmetrical concentrated masses, supported at corner points. In the case of several concentrated masses, by using the principle of superposition we may find the reduced coefficients of masses conveniently. Hence we can obtain the lowest eigenfrequencies of thin plates. In the paper a good many numerical calculating examples are illustrated.
