| Abstract: | The maximum static friction on the same cross sectional area and different shape rod immersed in the granular matter is studied experimentally.It is demonstrated that the static friction of the circle,square and flat rods are different in the same conditions.A model constituting of layers of granular matter which are symmetrically distributed is employed to analyze the experimental results qualitatively. |
