✦ Synopsis

The title problem is solved in the present study by using a very simple polynomial expression which identically satisfies the boundary conditions. A variational formulation is then applied and an approximate but extremely accurate and simple frequency equation is generated. Apparently the open literature does not contain a previous analytical treatment of the theme of the present paper as general and simple as the one presented here.
