Задача №16.12
Условие
Точильный станок приводится в движение педалью OA=24 см, которая колеблется около оси O по закону φ=(π/6)sin(πt/2) рад (угол φ отсчитывается от горизонтали). Точильный камень K вращается вокруг оси O1 с помощью стержня AB. Оси O и O1 перпендикулярны плоскости рисунка. Найти скорость точки D, лежащей на ободе точильного камня K радиуса R=2BO1, при t=0, если в этот момент OA и O1B расположены горизонтально.Решение
