El Ingeniero Mecanico

ENGINEERING is the profession that puts power and materials to work for man, Engineers use steel and concrete to construct building, dams, roads, and bridges. They use metal, glass, and plastics tomake hundreds of everyday products. Engineers transform water power info electricity that lights our homes and runs our factories. They harness the power of gasoline and other fuels that drive ourairplanes, train, ships and automobiles. Engineers themselves often discover or create. New materials and sources of power that serve man.
To put power and materials to work, and engineer must know anduse principles of science and mathematics. He must not only think clearly, but also speak and write clearly so that his instructions cannot be misunderstood. He has to study constantly to keep up withnew engineering developments.
In ancient times, there was no formal “engineering” education. Men built structures by trial and error they had to learn from their own mistakes. Today, special collegetraining prepares an engineer to work in a certain branch or field of engineering. Standards of quality and performance guide him on the job. A code of ethics regulates his professional conduct.Main Branches of Engineering
Most of the specialized kinds of engineering we know today developed during the past 200 years, Before that time, engineering dealt mostly with the construction of roads,bridges, canals, or military structures and devices. As man gained more knowledge of science and technology, engineers began to specialize in certain kinds of work. During the 1700’s and 1800’s, fivemain branches of engineering developed. They were: (1) civil engineering, (2) mechanical engineering, (3) mining and metallurgical engineering, (4) chemical engineering, and (5) electrical engineering.These main branches of engineering have been divided into many more specialized fields. The dividing lines between these fields are not always clear. For example, aeronautical engineering involves...
