This research was conducted over one Iranian variety of Oak (Quercus Persica)\nwith 70 observations. Physical and mechanical properties of oak are necessary for equipment\nused in activities such as transportation, storage, grading, packing etc. Properties which were\nmeasured include fruit dimensions, mass, volume, projected area, fruit density, geometric\nmean diameter, sphericity and surface area. Bulk density, porosity and also packing\ncoefficient were measured. Experiments were carried out at moisture content of 51.8% (w.b.).\nResults showed that average mass and volume were 12.95 g and 10.27 mL, respectively.\nDimensions increased from 41.85 to 61.09 mm in length, 14.45 to 25.02 mm in width and\n14.42 to 24.38 mm in thickness. The mean projected area perpendicular to length, width and\nthickness obtained 433.91, 1085.48 and 1115.46 mm2, respectively. The geometric mean\ndiameter and surface area were calculated as 27.638 mm and 2423.82 mm2, respectively,\nwhile sphericity was measured 51.78%. Elasticity modulus (E), maximum force which fruit\ncan support (Fmax) and work which performed to this force have been determined.
