Both bars have the same cross-sectional area 1 = 2 = with allowable tensile and compressive strengths of 20 and 15 respectively. As well, theta1 = theta2 = theta, and the dimension is constant. Determine the optimal design of this truss ( and theta) to obtain the minimum volume while satisfying the given stress constraints (this is the one we did in class). Use trial and error with an Excel spreadsheet and on your excel spreadsheet clearly indicate your design choice.
