Physical and Mechanical Properties of Mangifera indica (Mango) and Syzygium Spp. (Jamun) from Dehra Dun (U.P.)

Based on the tests carried out on small clear specimens, the physical and mechanical properties of Mangifera indica , Dehra Dun (U.P.) and Syzygium spp., Dehra Dun (U.P.) are presented. Nail/screw withdrawal resistance, safe working stresses for structural purposes and suitability indices for different industrial and engineering uses of both the species have also been reported alongwith the corresponding values of Mangifera indica , Puri (Orissa) and Syzygium spp., Cachar (Assam) and also Tectona grandi s (Malabar, Nilambur and Coimbatore) for comparison. The results have indicated that properties of both the species viz. Mangifera indica and Syzygium spp. tested from Dehra Dun (U.P.) are inferior in almost all the properties as compared to Mangifera indica , Puri (Orissa) and Syzygium spp., Cachar (Assam).
