In the case of P. japonica, according to Wakchaure (2012)WAKCHAURE, M. R. et al. Bambu: caracteristicas de construcao. In: FREIRE, W. J.; BERALDO, A. L. Tecnologias e materiais alternativos de construo. Campinas: Ed. Unicamp, 2003. p. 260-286., it is possible that the rate of radial shrinkage due to the temperature was higher in the bark, and the inner wood and bamboo culm were subjected to a higher shrinkage strain due to the higher tension in the longitudinal direction. So, it is possible that this would have been the location where the loss in the strength was the greatest, and this is corroborated by the findings.
A difficult subject can be approached in a straightforward manner when you know that some applications have been studied. In this book, the authors present various examples of physical and mechanical properties of some important materials, with the aim of helping students understand the concepts, and they present the theory in a consistent and concise manner. The Tenth SI Edition retains the hallmark features synonymous with the Hibbeler franchise, but has been enhanced with the most current information, a fresh new layout, added problem solving, and increased flexibility in the way topics are covered in class.
Core Science; previously named Basic Science (since 1989), is a science textbook written by David B. Hibbeler and Roberta S. Walker, and is the best-selling basic science text for introductory physics since 1989. In this new edition, the authors give students greater ownership of the material through a denser coverage of introductory physics principles and more supporting material that helps them create hands-on activities.
A similar result was observed for the section without node. In these two sections, as a result of the hydrothermal treatment, there was an increase in the tensile strength parallel to the fibers, for all studied species. This may be because during this treatment, the bamboo fibers are submitted to a thermal gradient, causing them to vibrate. This reaction and the expansion (dilatation) in the bamboo cell cause the death of insects (insects and fungi), which leads to an increase in the bamboo resistance ( Beraldo 2003BERALDO, A. L. et al. Bambu: caractersticas e aplicaes. In: FREIRE, W. J.; BERALDO, A. L. Tecnologias e materiais alternativos de construo. Campinas: Ed. Unicamp, 2003. p. 253-295. and Wakchaure & Kute 2012WAKCHAURE, M. R.; KUTE, S. Y. Effect of moisture content on physical and mechanical properties of bamboo. Asian Journal of Civil Engineering (Building and Housing), v. 13, n. 6, p. 753-763, 2012.).
Download Hibbeler Resistencia Dos Materiais 7 Ed Pdf In section P. aurea, no significant difference was observed among tensile strengths. This can be explained by the fact that the diameter of the section, in general, is greater than 100°, and it is possible that no significant variation in the length was made. The latter can be verified in Chung & Yu (2002)CHUNG, K. F.; YU, W. K. Mechanical properties of structural bamboo for bamboo scaffoldings. Engineering Structures, v. 24, n. 4, p. 429-442, 2002. where it was observed that the tensile strength parallel to the fibers of all species for the sections with and without node were similar.
