Задача №23.66

Условие

В условиях предыдущей задачи определить составляющие абсолютного ускорения точки M, движущейся вблизи Земли.

Решение




Предыдущая задача №65
Восточная, северная и вертикальная проекции скорости точки M относительно Земли соответственно равны vE, vN и vh. Определить проекции относительного ускорения точки на координатные оси x, y, z (ось x направлена на восток, ось y — на север, ось z — по вертикали), если высота ее над поверхностью Земли в данный момент равна h, а широта места φ (R и ω — радиус и угловая скорость Земли).
Следующая задача №67
Кривошипно-кулисный механизм приводного молота состоит из прямолинейной кулисы, совершающей возвратно-поступательное движение. Кулиса приводится в движение камнем A, соединенным с концом кривошипа OA=r=0,4 м, который вращается равномерно с угловой скоростью, равной 4π рад/с. При t=0 кулиса занимает нижнее положение. Найти ускорение кулисы.
