Comparison beech wood tension strength parallel to grain of cylindrical samples with conical and funnel tapering versus standard rectangular cross section samples

In this paper, the influence of shape samples on tension strength parallel to grain of beech wood have been analyzed. The cylindrical samples with conical tapering and with funnel tapering were used. Both types of cylindrical samples were compared with one-sided tapered standard samples with a rectangular cross-section. Experimental outcome indicates that cylindrical samples have higher tension strength than rectangular standard ones. Whereas shape of tapering in cylindrical samples (conical or funnel) was not statistically significant. Furthermore the presentation and reanalysis of data concerning use of cylindrical samples made of seven domestic wood species from the doctoral dissertation were performed. Comparison of that data with source data about tension strength of standard rectangular samples, have proven higher tension strength parallel to grain of cylindrical samples.
