Abstract:Tensile strength, a mechanical property of bamboo is less investigated. In this study, the moduli of rupture and elasticity (MOR and MOE) of neem seed oil-treated and control split-bamboo samples with specific gravity 0.89 and conditioned in the laboratory to 11.76 per cent moisture content were evaluated in conformity with modified ASTM D143-94 owing to bambooís nature. The results showed that MOR for control samples, samples soaked in oil at room temperature for 24 h and samples soaked in hot oil at 60oC for 4 h were 157.40, 153.83, and 130.16 N mm-2 respectively. MOE also Followed the same trend with values for control samples, samples soaked in oil at room temperature for 24 h and samples soaked in hot oil at 60oC for 4 h being 3452.31, 2125.22, and 2018.18 N mm-2 respectively. Energy at maximum load, load and extension at yield also followed this trend. Results of analysis of variance at 5 per cent level of significance showed that values for all the evaluated properties except those for energy at maximum load significantly varied between control and oil-treated samples. Fisherís Least Significant Difference was employed as a follow-up test to compare mean values at P<0.05.
