Question: During a maintenance process on the three-dimensional truss in Problem, the AB member is replaced with a member with the following properties: E = 28 X 106 psi and A = 2.246 in2. Using ANSYS, determine the deflection of each joint and the stresses in each member. Hint you may need to ask your instructor for some help with this problem or you may want to study (revisited) on your own to learn about how to assign different at-tributes to an element in ANSYS,
Problem: The three-dimensional truss shown in the accompanying figure is made of steel (E = 29 x 106 psi) and is to support the load shown in the figure. The Cartesian coordinates of the joints with respect to the system shown in the figure are given in feet. The cross-sectional area of each member is 3.093 in2. Using ANSYS, determine the deflection of each joint, the stresses in each member, and the reaction forces. Verify your results
