Solution C2-63 is given, shown in Figure C2.6, condition 3 from the book by S.M. Targa 1989. The structure consists of a rigid angle and a rod, which at point C can be hingedly connected to each other (Figures C2.0 - C2.5) or freely rest on each other (Figures C2.6 - C2.9). At point A, the structure can be connected either by a hinge or by a rigid connection. At point B, the external connection can consist of a smooth plane (Figures 0 and 1), a weightless rod BB´ (Figures 2 and 3), and a hinge (Figures 4-9). At point D, the external connection can consist of a weightless rod DD´ (Figures 0, 3, 8) or a hinged support on rollers (Figure 7). The structure is exposed to a pair of forces with a moment M = 60 kN m, a uniformly distributed load of intensity q = 20 kN/m and two other forces. The directions and points of application of these forces are indicated in Table C2, which also indicates the areas affected by the distributed load (for example, in conditions No. 1, the structure is subject to force F2, directed at an angle of 60° to the horizontal axis and applied at point L, force F4 , directed at an angle of 30° to the horizontal axis and applied at point E, as well as a uniformly distributed load in section CK). It is necessary to determine the reactions of the connections at points A, B, C (for Figures 0, 3, 7, 8 also at point D) caused by the given loads. For calculations, a = 0.2 m is assumed.
Our digital goods store presents solution C2-63, which contains Figure C2.6 of condition 3 from the book by S.M. Targa 1989. This digital product is presented in a beautiful html design that preserves the structure of the original drawing. The solution consists of a description of the structure, in which there is a rigid angle and a rod, as well as external connections at points A, B, C and D. Table C2 indicates the directions, points of application and areas on which the distributed load acts, as well as the forces causing reactions of bonds at these points. Solution C2-63 can be useful for the design and analysis of structures subject to forces and loads.

Solution C2-63 (Figure C2.6 condition 3 S.M. Targ 1989) is a structure that consists of a rigid angle and a rod connected to each other by hinges or freely resting on each other at point C. At point A or a hinge or a rigid embedment, and at point B there may be a smooth plane, a weightless rod BB´ or a hinge. At point D there may be a weightless rod DD´ or a hinged support on the rollers. The structure is acted upon by a pair of forces with a moment M = 60 kN m, a uniformly distributed load of intensity q = 20 kN/m, and two more forces, which are indicated in Table. C2. It also indicates where the distributed load operates. It is necessary to determine the reactions of the connections at points A, B, C (and at point D for Fig. 0, 3, 7, 8) caused by the given loads. For calculations, a = 0.2 m is assumed.
