| Abstract: | In this paper the fundamental differential equations are inferd to straight beam of gradual circular and rectangular section in bending free vibration. Some formulae about the solutions are obtained by using the analytical method, WRM, TMM, FEM etc.. It is suitable for engineers to use the methods on microcomputer. If we use the methods suggested in this paper, the designs of engineering structures will be much safer and more eecnomical. |
