Задача №16.28
Условие
Кривошипный механизм связан шарнирно в середине C шатуна со стержнем CD, а последний — со стержнем DE, который может вращаться вокруг оси E. Определить угловую скорость стержня DE в указанном на рисунке положении кривошипного механизма, если точки B и E расположены на одной вертикали; угловая скорость ω кривошипа OA равна 8 рад/с, OA=25 см, DE=100 см, ∠CDE=90° и ∠BED=30°.Решение
