Many of the available algorithms for solving the problems of nonlinear optimization have failed to yield results. This may be as a result of searching for solutions in an infeasible region or because the problem is ill-defined. In any case, there is no way for the designer to know that any of these situations exist ahead of time. However, Johnson’s method of optimum design is one algorithm that is capable of giving insight to the designer when a feasible solution may exist. This paper applies this method to the design of a piston rod. It is also demonstrated that using this method the designer can easily consider many types of materials in the design process without undue waste of time.
