To demonstrate your understanding of using the method of joints to analyze trusses, complete the following: - Part A) Determine the axial load (tension or compression) all members the truss

using hand calculations. • Part B) Model the truss in SAP2000. Give all members a cross-sectional area of 2.0 in^2 and I = 35in^4. Use the steel material(E = 29,000 ksi). Find all the bar forces and report them in a table. • Part C) Using the SAP2000, from Part B, change the cross-sectional area of all bars to A = 3.0 in^2. Find all the bar forces andreport them in a table. Part D) Based on your results from Parts A, B, and C comment on any similarities or differences in your results for thisdeterminate truss.
