Задача №16.14
Условие
Стержень OB вращается вокруг оси O с постоянной угловой скоростью ω=2 с-1 и приводит в движение стержень AD, точки A и C которого движутся по осям: A — по горизонтальной Ox, C — по вертикальной Oy. Определить скорость точки D стержня при φ=45° и найти уравнение траектории этой точки, если AB=OB=BC=CD=12 см.Решение
