Задача №25.10
Условие
Кривошип OC с помощью стержня AB приводит в движение ползуны A и B, которые скользят вдоль взаимно перпендикулярных направляющих x и y. Эти направляющие в свою очередь вращаются против хода часовой стрелки вокруг оси O с постоянной угловой скоростью ω (ω=π/2 рад/с). Угол поворота φ кривошипа OC, отсчитываемый от оси x против хода часовой стрелки, изменяется по закону φ=πt/4 рад. Найти модули абсолютной скорости и абсолютного ускорения точки M линейки AB в момент времени t=0, если OC=AC=CB=2BM=16 см.Решение
