(a) A criterion is required for selecting a material with the lowest cost in a strength-limited design for a cylindrical tie rod. Write the objective statement. Derive the criterion and identify the material index. The length of the tie rod, L, is fixed. (1 point) (b) A criterion is also required for selecting a material with the lowest cost in a strength-limited design for a square section beam (area b2). The length of the rod, L, is fixed. Write the objective statement and derive the criterion.
