Unformatted text preview: annot exceed $1,000. In addition to this budget condition, other engineering specifications must be maintained in the design: 1. The stress in any member of the truss cannot exceed the yield stress, fY . 2. In order to avoid the possibility of a buckling collapse, the compressive load in compression members cannot exceed the Euler critical buckling load, PCR . 3. The cross‐sectional area of any bar used in the construction cannot be less than 0.5 in2. Design Exercise Formulate the least cost engineering design of the truss as a linear programming problem. Use Excel Solver to identify the optimal (i.e., least cost) design. Rev...
