    If this is the calculation of the farm and will be at least the place of force application then I am ready to try.
    I doubt because. Instead of the calculation scheme in the task is given a sketch.

    Момент сопротивления кручению (или полярный момент) относится к геометрическим характеристикам, а метод предельных состояний относится к одному из методов прочностных расчетов элементов (сечений). Я так понял вас интересует мах.усилия (момент) на которое работает сечение? Если так, то напряжение в сечении не должно превышать Ry, значит  Ry >  Mmax / Wp + N/А (если N есть в задании) если нет то  Mmax < Ry * Wp. 

    Для вашего варианта 1: 

    Wp = 435,926 см.куб. image

    А далее, как вы говорите, ответ найти не сложно.
