A team of design engineers are designing an amusement park structure as in Figure 2below. The horizontal beam supporting the gondolas at both ends are supported by 2vertical bars, bar EB and bar CF with a cross sectional area of 11,100mm2 and 9,280mm2each. Gondola 1 (left) weighs 380 kN and Gondola 2 (right) weighs 360kN respectively. Due to theweight of both the gondolas, the design team needs to investigate the verticaldisplacements of both ends of the horizontal beam at A and D. You are required to helpthem analyze and calculate the vertical displacement at both ends due to the weight ofthe gondolas.

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me? 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 to determine the following: 1) Draw a free-body diagram of the structure 2) Simplify the Free…
