Задача №23.57

Условие

Решение




Предыдущая задача №56
Река Нева течет с востока на запад по параллели 60° северной широты со скоростью vr=1,11 м/с. Определить сумму проекций на касательную BC к соответствующему меридиану тех составляющих ускорений частиц воды, которые зависят от скорости течения. Радиус Земли R=64*105 м.
Следующая задача №58
Найти абсолютное ускорение шаров центробежного регулятора Уатта, если он вращается вокруг своей вертикальной оси, имея в данный момент угловую скорость ω=π/2 рад/с при угловом ускорении ε=1 рад/с2; угловая скорость расхождения шаров ω1=π/2 рад/с при угловом ускорении ε1=0,4 рад/с2. Длина рукояток шаров l=0,5 м, расстояние между осями их привеса 2e=0,1 м, угол раствора регулятора в рассматриваемый момент 2α=90°. Размерами шаров пренебречь, принимая шары за точки.
