The solution to problem C1-84 (shown in Figure C1.8 in condition 4 from the book by S.M. Targ published in 1989) assumes the presence of a rigid frame located in a vertical plane (see Figures C1.0-C1.9 and Table C1 ). The frame is hinged at point A, and at point B it is attached either to a weightless rod with hinges at the ends, or to a hinged support on rollers. At point C, a cable is attached to the frame, thrown over a block and carrying at the end a load weighing P = 25 kN. The frame is acted upon by a pair of forces with a moment M = 100 kN m, as well as two forces, the values, directions and points of application of which are indicated in the table (for example, in conditions No. 1, the frame is acted upon by a force F2 applied at an angle of 15° to the horizontal axis at point D, and force F3 applied at an angle of 60° to the horizontal axis at point E, etc.). It is necessary to determine the reactions of the connections at points A and B caused by the acting loads. For final calculations, a = 0.5 m is accepted.

Solution C1-84 (Figure C1.8 condition 4 S.M. Targ 1989) is a structure with a rigid frame located in a vertical plane. The frame is hinged at point A, and at point B it is attached either to a weightless rod with hinges at the ends, or to a hinged support on rollers. At point C, a cable is attached to the frame, thrown over a block and carrying at the end a load weighing P = 25 kN.
A pair of forces with a moment M = 100 kN m and two forces act on the frame, the values, directions and points of application of which are indicated in the table. For example, in condition No. 1, the frame is subject to a force F2 at an angle of 15° to the horizontal axis, applied at point D, and a force F3 at an angle of 60° to the horizontal axis, applied at point E.
It is necessary to determine the reactions of the connections at points A and B caused by the acting loads, provided that a = 0.5 m.
