The structure in Figure 1 consists of a frame, two pulleys, one at B and another at C, and two wires(E-F and G-D). The frame is pinned to a wall by a single shear pin at A. The two wires are attachedto F, G, and D, and subjected to a downward vertical force of 75 lb at E. Note that the pulleys atB and C are assembled to the frame by double shear pins. The diameters of wires E-F and G-D are1 in and 1.5 in, respectively.1.6 ftBE75 lb4 ftG2 ft0.6 ftC2 ft5 ftDAFig. 1 Structure with pulliesa) Find expressions for normal force, shear force and bending moment diagrams as functionsof x measures from point B for the straight section A-B in the frame and plot thecorresponding diagrams.

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me answer all the questions below? Especially the one about the bending moment and shear force. The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy. Assume that the weight of the child is equally distributed across all of the points indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required…
