Description
- Solution C2-23 (Figure C2.2 condition 3 SM Targ 1989)
- The design consists of a hard corner and a rod, which are either hinged at point C (Figure C2.0-C2.5) or are freely supported against each other (Figure C2.6-C2.9). The external constraints imposed on the structure are at the point A or hinge, or rigid sealing; at point B or a smooth plane (Figures 0 and 1), or a weightless rod BB ´(Figures 2 and 3), or a hinge (Figures 4-9); at point D or the weightless rod DD ´(Figures 0, 3, 8), or the hinged support on the rollers (Figure 7). Each structure is affected by: a pair of forces with a torque M = 60 kN · m, a uniformly distributed intensity load q = 20 kN / m and two more forces. These forces, their directions and points of application are indicated in Table. C2; In the same column in the column "Loaded area" it is indicated where the distributed load is acting (for example, under conditions No.1, the force F2 at an angle of 60 ° to the horizontal axis applied at point L, force F4 at an angle of 30 ° to the horizontal axis , applied at point E, and the load distributed in section CK). Determine the reactions of bonds at points A, B, C (for Figures 0, 3, 7, 8 also at point D), caused by given loads. In the final calculations, take a = 0.2 m.
