ENGINEERING

1. Engineering is the professional art of applying science to the optimum conversion of the resources of nature to the uses of humankind. The word engine is derived from the Latin root ingenerare, which means «to create». The engines of war were devices such as catapults, floating bridges, and assault towers; their designer was the «engineer», or military engineer. The counterpart of the military engineer was the civil engineer, who applied essentially the same knowledge and skills to designing buildings, streets, water supplies, sewage systems, and other projects.

2. The function of the scientist is to know, while that of the engineer is to do. The scientist adds to the store of verified, systematised knowledge of the physical world; the engineer brings this knowledge to bear on practical problems. Engineering is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, transfer and rate processes, and systems analysis.

3. Unlike the scientist, the engineer is not free to select the problem that interests him; he must solve problems as they arise; his solution must satisfy conflicting requirements. Usually efficiency costs money; safety adds to complexity; improved performance increases weight. The engineering solution is the optimum solution, the end result that is most desirable. It may be the most reliable within a given weight limit, the simplest that will satisfy certain safety requirements, or the most efficient for a given cost. In many engineering problems the social costs are significant.

4. Engineers employ two types of natural resources - materials and energy. Materials are useful because of their properties: their strength, ease of fabrication, lightness, or durability; their ability to insulate or conduct; their chemical, electrical, or acoustical properties. Important sources of energy include fossil fuels, wind, sunlight, falling water, and nuclear fission. Since most resources are limited, the engineer must concern himself with the continual development of new resources as well as the efficient utilisation of existing ones.

ASSEMBLY LINE

1. An assembly line is industrial arrangement of machines, equipment, and workers for continuous flow of workpieces in mass-production operations. It is designed by determining the sequences of operations for manufacture of each product component as well as the final product. Each movement of material is made as simple and short as possible. Work assignments, numbers of machines, and production rates are programmed so that all operations performed along the line are compatible.

2. An automotive assembly line starts with a bare chassis; components are attached successively as the growing assemblage moves along a conveyor. Parts are matched into subassemblies on feeder lines that intersect the main line to deliver body parts, engines, and other assemblies. As the units move past, each worker along the line performs a specific function. Each part and tool is delivered to its point of use in synchronisation with the line. A number of different assemblies are on the line simultaneously, but an intricate system of scheduling and control ensures that the appropriate body type and colour, trim, engine, and optional equipment arrive together to make the desired combinations.

3. Automated assembly lines consist entirely of machines run by machines. In such continuous-process industries as petroleum refining and chemical manufacture and in many modern automobile-engine plants, assembly lines are completely mechanised and consist almost entirely of automatic, self-regulating equipment.

4. Most products, however, are still assembled by hand because many component parts are not easily handled by a simple mechanism. The number of products automatically assembled is steadily increasing but at a low rate because a product must be designed for automatic assembly and must be accurately and consistently manufactured. Expensive and somewhat inflexible, automatic assembly machines are economical only if run at very high outputs. However, the development of versatile automatic machinery and industrial robots is increasing the flexibility of fully automated assembly operations.
