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.
