Задача №5.17
Условие
Груз B веса P удерживается в равновесии при спуске по шероховатой поверхности, имеющей форму четверти кругового цилиндра. Коэффициент трения между поверхностью и грузом f=tgφ, где φ — угол трения. Определить натяжение троса S как функцию угла α. В каких пределах может меняться натяжение троса при равновесии груза B? Размерами груза и блока пренебречь.Решение
