hi this only problem solving truss analysis question so no reference . please let me know if can be done or not before doing the payment unlike last time please.


Take-Home Question (Truss Analysis) – Portfolio 2 (6%) THESE QUESTIONS ARE TO BE COMPLETED INDIVIDUALLY All submissions are to be in a PDF format. Your answers may be typed or handwritten. If you are handwriting your submission please use apps such as Adobe Scan, Genius Scan or CamScanner to produce a quality scan of your working. DO NOT UPLOAD JPEGs. Please submit your single PDF file by 11:59pm on Friday the 4th of September. The truss structure is loaded as shown in Figure 1. The members are made of 304 stainless steel which has a yield stress of 510 MPa. The cross-section of each member is the same and can be seen below: Figure 1 – Truss Structure and Cross Section of Members Based on the information above, answer the following questions: 1. Solve the force in each member of the truss using method of joints. For each member, state if it is in tension or compression. Using the rules provided in the lecture, identify any zero forces members (state what rule you use). and identify the worst case tension and compression members. (3 marks) 2. For the worst case tension and compression members identified in the previous question, calculate the corresponding stress and determine if it will satisfy a safety factor of 2.1 (1.5 marks) 3. Conceptual Question: We now decide to consider the self-weight of the truss. Determine how you would apply the self-weight so you can analyse the structure. This can be done in many ways, please draw an FBD for one of them. Justify your answer and why you believe it is valid. You do not need to do calculations (1.5 marks) * Show all your working *
