Условие
Подвеска состоит из двух балок AB и CD, соединенных шарнирно в точке D и прикрепленных к потолку шарнирами A и C. Вес балки AB равен 60 Н и приложен в точке E. Вес балки CD равен 50 Н и приложен в точке F. В точке B к балке AB приложена вертикальная сила P=200 Н. Определить реакции в шарнирах A и C, если заданы следующие размеры: AB=1 м; CD=0,8 м; AE=0,4 м; CF=0,4 м; углы наклона балок AB и CD к горизонту соответственно равны: α=60° и β=45°.Решение
