Задача №23.19

Условие

Решить предыдущую задачу для случая криволинейного канала, если радиус кривизны канала в точке C равен ρ, а угол между нормалью к кривой AB в точке C и радиусом OC равен φ. Радиус CO равен r.

Решение




Предыдущая задача №18
Компрессор с прямолинейными каналами равномерно вращается с угловой скоростью ω вокруг оси O, перпендикулярной плоскости рисунка. Воздух течет по каналам с постоянной относительной скоростью vr. Найти проекции абсолютной скорости и ускорения на оси координат для частицы воздуха, находящейся в точке C канала AB, при следующих данных: канал AB наклонен к радиусу OC под углом 45°, OC=0,5 м, ω=4π рад/с, vr=2 м/с.
Следующая задача №20
Выразить как функцию времени угловое ускорение ε качающейся кулисы поперечно-строгального станка, если кривошип длины r вращается равномерно с угловой скоростью ω; расстояние между осями вращения кривошипа и кулисы a>r. (См. рисунок к задаче 21.13.)
