Question
A two-bar truss is to be designed to carry a load of 2W as shown in Fig. 1.25. Both
bars have a tubular section with mean diameter d and wall thickness t. The material
of the bars has Young's modulus E and yield stress oy. The design problem involves
the determination of the values of d and t so that the weight of the truss is a minimum
and neither yielding nor buckling occurs in any of the bars. Formulate the problem as a
nonlinear programming problem.
