DESCRIPTION

This assignment involves the analysis of a three-dimensional aluminum truss structure supporting a 1000 lb sign. Utilizing ANSYS software, you will calculate the deflection at joint E, determine the stress in each member, and assess the reaction forces. The truss is defined by its member cross-sectional area of 3.14 in² and elastic modulus of 10.4 x 10⁶ lb/in². Joint coordinates are provided for accurate modeling. Submit your analysis by September 26.

  1. Computer-Aided Engineering Design Assignment 4 Due on September 26

  2. 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.
