For the following problems use an allowable stress equal to 25 ksi for bothtension and compression. Calculate the volume of the truss.PART A. Use the beam-truss analogy to design the following truss.PART B. Perform the structural analysis of the truss and design each member using itsactual internal force. Compare the truss volume to the one of PART A. The image illustrates a truss structure supported at points A and E, with a series of interconnected members labeled from J to F. The truss spans a total length of 48 feet, divided into four 12-foot segments between the joints B, C, D, and E.**Structure Details:**- **Support Points:** - Point A: Fixed support on the left. - Point E: Roller support on the right.- **Members and Joints:** - The members are connected sequentially at the joints indicated by letters J, I, H, G, and F.- **Forces:** - A downward force of 6 kips is applied at joint B. - A downward force of 8 kips is applied at joint C. - A downward force of 6 kips is applied at joint D.- **Height:** - The vertical distance from joint F to joint J is 9 feet.The truss is designed to evenly distribute loads across the structure, which is crucial in civil engineering applications to ensure stability and safety. Understanding the distribution of forces and the support system helps in analyzing the structural integrity of bridges, roofs, and similar constructions.
