Question: The three-dimensional truss shown in the accompanying figure is made of aluminum alloy (E = 10.9 x 106 psi) and is to support a load of 500 lb. The Cartesian coordinates of the joints with respect to the coordinate system shown in the figure are given in feet. The cross-sectional area of each member is 2.246 in2. Using ANSYS, determine the deflection of each joint, the stress in each member, and the reaction forces. Knowing that the second moment of area is 4.090 ins. do you think that buckling is a concern for this truss? Verify your results.
