      <abstract xml:lang="ru">
        <p>Рассматривается идеально упругая сфера, материал которой подвержен только действию силы притяжения своей массы. Тогда предполагается, что в сфере есть несжимаемое ядро. Предполагая, что толщина оболочки мала по отношению к радиусу сердечника, получается формула для напряжений в меридиональных сечениях, полученная ранее разными авторами (в том числе - Академик Бынник) для совершенно разных предположений.</p>

      <abstract xml:lang="en">
        <p>We consider a perfectly elastic sphere, the material of which is subject only to the gravitational attraction of its own mass. It is then assumed that the sphere contains an incompressible core. Assuming that the thickness of the shell is small relative to the radius of the core, we obtain a formula for the stresses in meridional sections, which was previously derived by various authors (including Academician Bynnik) under entirely different assumptions.</p>
