Solution C4-75 (Figure C4.7 condition 5 S.M. Targ 1989)

In problem C4-75 from the textbook S.M. Targa (image C4.7, condition 5, 1989) there are two homogeneous rectangular thin slabs, rigidly connected at right angles and secured with hinges and rods at points A and B. The dimensions of the slabs are indicated in the figure, and the weight of each slab is also known ( P1 = 5 kN, P2 = 3 kN). Each plate is located parallel to one of the coordinate planes (the xy plane is horizontal). The plates are acted upon by a pair of forces with a moment M = 4 kN m, lying in the plane of one of the plates, and two forces. The values ​​of these forces, their directions and points of application are indicated in Table C4. Forces F1 and F4 lie in planes parallel to the xy plane, force F2 in a plane parallel to xz, and force F3 in a plane parallel to yz. The points of application of forces (D, E, N, K) are located in the corners or in the middle of the sides of the slabs. It is necessary to determine the reaction of the bonds at points A and B and the reaction of the rod (rods). In the calculations, a = 0.6 m is assumed. Options for fixing the plates may differ: in Figures C4.0-C4.7, one hinge (at point A), one bearing (at point B) and one weightless rod (1) are used, in while in Figures C4.8 and C4.9 two bearings (at points A and B) and two weightless rods (1 and 2) are used.
