An analytical method has been created for calculating Young’s and shear moduli of object’s material based on data of such tests. In Timoshenko approximation, we consider problems of bending a beam one or both ends of which lie on elastic Winkler foundations. The obtained solutions are used to eliminate uncertainties in the calculation of elastic moduli that arise when the conditions of fixing an object (console or bridge) on the edges of a recess in the substrate are unknown.</p></abstract><trans-abstract xml:lang="ru"><p>Усовершенствована методика АСМ–испытаний подвешенного нанообъекта на изгиб. Создан аналитический способ расчета модулей Юнга и сдвига материала объекта по данным таких испытаний. В приближении Тимошенко рассмотрены задачи об изгибе балки, один или оба конца которой лежат на упругих основаниях Винклера. Полученные решения использованы для устранения неопределенностей в расчете упругих модулей, возникающих, когда неизвестны условия закрепления объекта (консоли или мостика) на краях углубления в подложке.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атомно-силовая микроскопия</kwd><kwd>изгиб</kwd><kwd>упругие модули</kwd><kwd>упругое основание Винклера</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atomic force microscopy</kwd><kwd>bending</kwd><kwd>nanoscroll</kwd><kwd>elastic moduli</kwd><kwd>elastic Winkler foundation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation, project no. 19-1300151</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Binnig G., Quate C.F., Gerber Ch.
