Task id16437
A homogeneous rod AB of mass m1 = 40 kg, located at an angle a = 30° to the horizontal, one end A rests on a bearing with a horizontal axis of rotation, and the other is tied to a thread fixed at point C, located on the same vertical with point A so, that triangle ABC is equilateral (Fig.). A load of mass m2 = 90 kg is suspended from the rod AB at point D (at a distance of 1/3 of its length from point B). Find the tension force of the thread T. Neglect friction in the bearing.
