Studies on the Influence of Moisture and Spedfic Gravity on the Strength Properties of Mango Wood (Mangifera indica)

Abstract

Influence of moisture and specific gravity on the strength of mango wood is
discussed. The co-efficient of correlation between specific gravity and breaking
strength was found to be nonsignificant. The relation of strength and moisture
was found to be highly significant. The mean strength values indicated a reduction
in strength when the moisture increased from 8.5 to 18.8 %. However no
appreciable diff~rence in strength values could be observed when moisture increased above 37%. The strength-moisture relationship is a straight line, passing
approximately through the fibre saturation point. By using the exponential
formula, the breaking strength corresponding to any moisture level between zero
and fibre saturation can be determined.
