      <abstract xml:lang="ru">
        <p>Будем рассматривать случай, когда прокатывается брусок с прямоугольным сечением. 1. Определим в зависимости от давления на валки давление на единицу поверхности металла, предполагая это давление равномерным. Иначе говоря, определим среднее давление на единицу поверхности металла (см. статью). 2. Вычислим механическую полезную работу при одном проходе бруска между валками. Под полезной работой мы понимаем здесь работу, которая затрачивается собственно на изменение формы бруска.</p>

      <abstract xml:lang="en">
        <p>We shall consider the case when a bar with a rectangular cross-section is rolled. 1. We determine, depending on the pressure on the rolls, the pressure per unit area of the metal, assuming this pressure to be uniform. In other words, we determine the average pressure per unit area of the metal (see the article). 2. We calculate the useful mechanical work for a single pass of the bar between the rolls. By useful work we understand here the work that is expended specifically on changing the shape of the bar.</p>
