An inverted J-shaped rod is used for a street lamp-post. Assuming such a rod is constituted of a straight line and an arcuate portion, the dimensionless natural frequency and the natural vibration mode are obtained when the rod makes a transverse vibration in a plane containing the center line of the rod. The vibration equation is obtained by the use of Hamilton's Principle. Since the frequency equation is a transcendental equation, the dimensionless natural frequency calculated by a computer is shown in the drawing. Both ends of the rod are assumed to be respectively fixed-fixed, fixed-hinged, fixed-rolled or fixed-free. To eliminate the effect of rotational inertia and shearing deformation, a large slenderness ratio is given to the rod.
