N2  - Mechanical engineering is the branch of engineering that is concerned with the conversion of energy and with the design of machines. The designer of machines is a versatile person, not a specialist, because he must have knowledge of science, "to know," and a knowledge of engineer-ing, "to produce." For instance, the design of the machinery for missile launching requires, in part, considerable knowledge of physics, mechanics, aerodynamics, performance of materials in high-intensity, short-time use, electronics, and safety requirements.

The engineering design process begins with the awareness of a human need or want. In Fig. 1-1, this is indicated as the GOAL (1). The goal should be stated in words as clearly as possible at this stage of the design process. When the goal is stated in general terms, it is then necessary to develop more specific and quantitative information which determines the TASK SPECIFICATION (2) necessary to achieve the goal. The next step is the framing of a CONCEPT (3) with which the final form
