Задача №54.1

Условие

Жесткий стержень OB длины l может свободно качаться на шаровом шарнире около конца O и несет шарик веса Q на другом конце. Стержень удерживается в горизонтальном положении посредством нерастяжимого вертикального шнура длины h. Расстояние OA=b. Если шарик оттянуть перпендикулярно плоскости рисунка и затем отпустить, то система начнет колебаться. Пренебрегая массой стержня, определить период малых колебаний системы.

Решение




Следующая задача №2
Определить период малых колебаний астатического маятника, употребляемого в некоторых сейсмографах для записи колебаний почвы. Маятник состоит из жесткого стержня длины l, несущего на конце массу m, зажатую между двумя горизонтальными пружинами жесткости k с закрепленными концами. Массой стержня пренебречь, и считать пружины в положении равновесия ненапряженными.
