In the vibrations of frame work cosisting of many bars we must generally consider three kinds of displacements: torsional displacement, extensional, and flexural.　In order to solve simultaneously the equations for these displacements under the boundary conditions and the equations of continuity, we minimize the La-grangian represented by unknown boundary constants, and, consequently, obtain the equations to decide the frequencies and the boundary constants.　If the slenderness ratio of each bar is large enough, then it is usually assumed to be infinite in the computations of those equations. And this assumption introduces some modifications of the terms referring to the torsional vibration and extensional one.　In this paper, we shall be able to find the physical meaning of the dynamical system corresponding to the vibrations of frame work under those modifications
