Abstract :The volumetrical, geometrical and frictional properties of silver berry fruits ( Elaeagnus angustifolia L.) determined. The mean values of the fruit mass, porosity, fruit volume, fruit and bulk densities values of silver berry fruits were found as 1.06 g, 71.7%, 1.13 cm 3 , 934.4 kg/m 3 and 264.7 kg/m 3 , respectively. The mean values of the surface area, sphericity and geometric mean diameter and were 5.46 cm 2 , 71.4%, and 13.0 mm, respectively. The mean values of dynamic and static coefficient of friction against plywood, chipboard, galvanized steel, rubber and mild steel surfaces were determined and the highest dynamic and static coefficients of friction values of silver berry fruits were found for rubber surface.  The angle of repose was found as 7.37° for silver berry fruits.
Keywords : Oleaster, surface area, angle of repose, static coefficient of friction
