%X <p>The dependence of elastic and tensile properties of coniferous trees on the share of summer wood can be presented as linear functions, if the soft wood is considered as a statically indefinite structure. By eliminating the share of summer wood by a certain function presented in the article, the elastic and tensile properties are the linear functions of density.</p><p>The functions are proved right by conducting strength tests on pine. Practical implications of the derived functions in rating the quality of wood are also presented.</p><p>The PDF contains a summary in Finnish. </p>
