Solution C4-68 (Figure C4.6 condition 8 S.M. Targ 1989)

In problem C4-68 (Figure C4.6 condition 8 S.M. Targ 1989) there are two homogeneous rectangular thin plates that are rigidly connected (welded) at right angles to each other. They are secured using a spherical hinge (or thrust bearing) at point A, a cylindrical hinge (bearing) at point B and a weightless rod 1 (Fig. C4.0 - C4.7). Alternatively, the plates can be secured by two bearings at points A and B and two weightless rods 1 and 2 (Fig. C4.8, C4.9). All rods are attached to the slabs and fixed supports with hinges. The dimensions of the plates are indicated in the pictures.

Slab P1 has a weight of 5 kN and slab P2 has a weight of 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. In this case, 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). When calculating, a = 0.6 m is taken.

Solution C4-68 is a digital product designed to solve mechanical problems. This product contains information about solving problem C4-68 from the book by S.M. Targa "Mechanics. Problems" (1989).

Problem C4-68 describes a situation in which there are two homogeneous rectangular thin plates, rigidly connected at right angles to each other and secured by hinges and rods. Several forces act on the slabs, and it is necessary to determine the reactions of the bonds at points A and B and the reaction of the rod(s).

Solution C4-68 includes a detailed description of the problem, illustrations, and tables with data on forces, directions, and points of application. The product also contains detailed calculations and answers to the questions posed in the problem.

This product is intended for students and teachers involved in mechanics and solving problems in physics.

Solution C4-68 (Figure C4.6 condition 8 S.M. Targ 1989) is a digital product designed to solve problems in mechanics. This product contains information about a problem that describes a situation in which there are two uniform rectangular thin plates rigidly connected at right angles to each other and secured by hinges and rods. Several forces act on the slabs, and it is necessary to determine the reactions of the bonds at points A and B and the reaction of the rod(s).

The problem uses two options for securing the plates: one with a weightless rod and one hinge, and the other with two weightless rods and two bearings. In both cases, the rods are attached to the slabs and to the fixed supports with hinges. The dimensions of the slabs are indicated in the figures, and the weight of the larger slab P1 = 5 kN, the weight of the smaller slab P2 = 3 kN. Each of the plates is located parallel to one of the coordinate planes (the xy plane is horizontal).

The C4-68 solution is a structure of two homogeneous rectangular thin slabs, rigidly connected at right angles to each other. The plates are fixed by a spherical hinge at point A, a cylindrical hinge at point B and a weightless rod 1 or two weightless rods 1 and 2. All rods are attached to the plates and to fixed supports by hinges.

The dimensions of the slabs are shown in the figures, and the weight of the larger slab P1 is 5 kN, and the weight of the smaller slab P2 is 3 kN. Each of the plates 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 F1 and F4, lying in planes parallel to the xy plane. Force F2 lies in a plane parallel to xz, and force F3 lies in a plane parallel to yz. The values ​​of these forces, their directions and points of application are indicated in table C4, and the points of application of forces (D, E, H, 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). When calculating, take a = 0.6 m.
