   <abstract xml:lang="ru">
    <p>В работе авторы рассматривают задачу определения упругой линии сжимаемого продольной силой стержня, расположенного между двумя жесткими стенками. Изучают зависимость упругой линии и величин критических нагрузок от различных граничных условий. Получены точные решения задачи в нелинейной постановке.</p>

    <p>The paper considers the problem of determining the elastic&#13;
line of a rod compressed by a longitudinal force, located between&#13;
two rigid walls. The dependence of the elastic line and&#13;
the values of critical loads on various boundary conditions is&#13;
studied. Exact solutions of the problem in a nonlinear formulation&#13;
are obtained.</p>
