Задача №18.17
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 (см. рисунок к задаче 16.12). Найти в момент времени t=0 ускорение точки B точильного камня K, если O1B=12 см. В этот момент OA и O1B расположены горизонтально, причем ∠OAB=60°.Решение
