The three-dimensional truss shown in the accompanying figure is made of aluminum alloy (E=10.4 x 106 lb/in2) and is to support a sign weighing 1000 lb. The Cartesian coordinates of the joints with respect to the coordinate system shown in the figure are given in feet. The cross-section area of each member is 3.14 in2 Using ANSYS, determine the deflection of joint E, the stress in each member, and reaction forces.
