Задача №38.4

Условие

Решение




Предыдущая задача №3
Вычислить кинетическую энергию кулисного механизма, если момент инерции кривошипа OA относительно оси вращения, перпендикулярной плоскости рисунка, равен J0; длина кривошипа равна a, масса кулисы равна m, массой камня A пренебречь. Кривошип OA вращается с угловой скоростью ω. При каких положениях механизма кинетическая энергия достигает наибольшего и наименьшего значений?
Следующая задача №5
Вычислить кинетическую энергию кривошипно-ползунного механизма, если масса кривошипа m1, длина кривошипа r, масса ползуна m2, длина шатуна l. Массой шатуна пренебречь. Кривошип считать однородным стержнем. Угловая скорость вращения кривошипа ω.
