Abstract

In this investigation physical and mechanical properties of oak (Quercus castaneaefolia C.A. Mey) in Sangdeh region of Caspian Forests were measured according to the ASTM Standard D-143-83 for small samples. Statistical analysis included the performing of factorial design and Duncan's multiple- range test.
The results indicated that geographical direction on the stems were not significant sources of differences for physical and mechanical properties, but the effects of height of stems were great and statistically significant and in most cases properties decreased with increasing height.
