Solution C1-72 (Figure C1.7 condition 2 S.M. Targ 1989)

A rigid frame located in a vertical plane (Fig. C1.0 - C1.9, Table C1) 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 and 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 at an angle of 15° to the horizontal axis, applied at the point D and a force F3 at an angle of 60° to the horizontal axis applied at point E, etc.). Determine the reactions of connections at points A, B caused by acting loads. For final calculations, take a = 0.5 m.

It is necessary to determine the reactions of the connections at points A and B, caused by the acting loads on a rigid frame located in a vertical plane. The frame is hinged at point A, and at point B it is attached to a weightless rod with hinges at the ends, or to a hinged support on rollers, depending on the conditions of the problem. At point C, a cable with a load weighing P = 25 kN, thrown over a block, is attached to the frame. 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. In conditions No. 1, the frame is subject to a force F2 applied at point D at an angle of 15° to the horizontal axis, and a force F3 applied at point E at an angle of 60° to the horizontal axis, etc. For final calculations, a = 0.5 m should be taken.

Solution S1-72 is an electronic version of the problem with a picture and condition from the textbook “Collection of problems in theoretical mechanics” by S.M. Targa, published in 1989. The problem considers a rigid frame located in a vertical plane and hinged at point A, and at point B attached to a weightless rod with hinges at the ends, or to a hinged support on rollers. At point C, a cable with a load weighing P = 25 kN, thrown over a block, is attached to the frame. 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.

Solution C1-72 includes a detailed description of the solution to the problem with a step-by-step explanation of each step. For clarity, graphic images of the frame and forces are provided, as well as a table indicating the values, directions and points of application of the forces. For final calculations, the value a = 0.5 m is used.

Solution C1-72 (Figure C1.7 condition 2 S.M. Targ 1989) is a structure consisting of a rigid frame hinged at point A and attached at point B to a weightless rod with hinges at the ends or to a hinged support at skating rinks 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.

The task is to determine the reactions of connections at points A and B caused by acting loads. When calculating, it is necessary to take the frame length a = 0.5 m.
