Abstract

In the lateral vibration of an elastic bar, the natural frequency varies during the transferring of its support and presents definite numbers of definite maximum and minimum values in accordance with a general rule. In this paper the reality of this rule is first verified by an example of a canti-lever beam. Then the generality of this rule is ascertained by the aid of the solution of the integral equation in the forced vibration of a bar, and the meaning and interpretation of the rule are expressed in view of Rayleigh's principle.
