Ngth Reduce Part Upper Part Cummulated Mean and STDEV The position inside the cross section referred to in Tables three has the following which means: core zone = H3, middle zone = H2 and H4, outer zone = all other pieces of lumber (S1 and S2 for solid wood, and 10 for bonded parts) (see Figure 2).A fantastic correlation between the density plus the bending properties on the solid wood samples was noticed, as talked about in reference [7]: the bending properties improved with increasing density from the central element with the log towards the outer area, as illustrated within the example provided in Figure 7, according to the information obtained from Log N 1 samples, tangentially loaded; dissimilarly, the glued samples (represented with “x” and bold values in Figure 7) had decrease bending properties regardless of having greater density (due to the presence from the adhesive); As far because the influence from the position within the tree height is concerned, no significant distinction was noticed among the values obtained from the butt logs in comparison to the major logs for the density with the strong wood samples, which can be also in great accordance with information from reference [7]; the MOR and MOE values for strong wood are significantly less uniform; there is certainly a clear decreasing tendency of both parameters from butt to leading, as illustrated inside the instance offered in Figure eight, determined by the data obtained from Log N 1 samples, radially loaded; the glued samples obtained in the identical log (represented with “x” in Figure eight) showed incredibly close density, reduced MOR and MOE in the butt, and visibly higher MOR and MOE at the best, compared to the solid wood samples.Appl.
