In this paper, the relation between the applied load distribution and the natural frequency of vibration of some structural elements is presented. In this paper, the effects of the loading sizes on the natural frequency of vibration of some structural elements is presented. Many junior engineers get confused on such relations. This method extended to two dimensional problems including advanced composite laminated structures. It is hoped that this paper gives some guideline to such junior engineers.
