Jack A. Collins (Author of Mechanical Design of Machine Elements and Machines)

The essence of engineering especially mechanical design is the fulfillment of human needs and desires. Unfortunately, an absolute optimum can rarely be achieved because the criteria of performance, life, weight, cost, etc. Designers must not only compete in the marketplace, but must respond to the clear and growing obligation of the global technical community to conserve resources and preserve the environment. Finally, iteration, or cut-and-try pervades design methodology. Selection of the best material and geometry are typically completed through a series of iterations. List several factors that might be used to judge how well a proposed design meets its specified objectives. In a machine design context, adequate design may therefore be defined as the selection of material and geometry for a machine element that satisfies all of its specified functional requirements, while keeping any undesirable effects within tolerable ranges.
