Задача №25.4
Условие
Коническая шестерня M приводится в движение по шестерне N с помощью оси OC, закрепленной в точке O и вращающейся вокруг вертикальной оси z с постоянной угловой скоростью 2 рад/с. Горизонтальная платформа P, к которой прикреплена шестерня N, движется ускоренно вертикально вниз, имея в данный момент скорость v=80 см/с и ускорение w=80√3 см/с2. Угол BOA=60°, диаметр AB шестерни M равен 20 см. Найти абсолютные скорости и ускорения точек A и B шестерни M.Решение
