Abstract

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 grandis (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).

Abstract

Physical and Mechanical properties in green, air dry and kiln dry conditions based upon tests conducted on small clear specimens obtained from ten logs of Bischofia javanica (Uriam) from Arunachal Pradesh have been reported. The results obtained have been compared with 'Standard Teak' (from Malabar, Nilambur and Coimbatore). Suitability indices have been reported. And compared with the coresponding values of'Standard Teak'. Expected values based on specific gravity-strength relationship have also been reported for the sake of comparison.
