Engineering through the ages Different Disciplines & “clever inventions”

The Concept of Engineering Ingenious people have been developing tools and objects for thousands of years (4000 BC) Ancient inventions like the pulley, lever, and wheel were based on basic mechanical principles.

Engineers = Clever Inventors “Engineer” came into use in 1324 and means “a constructor of military engines” “Engine” at the time meant military machine “Engine” derives from the Latin word “ingenium” which means “clever invention”

Military Engineering Military Engineer The scale of inventions changed when Military Engineers started creating machines for warfare. Basic mechanisms like Wheels, levers, and pulleys soon became components in catapults, trebuchets, cannons, guns and cruise missiles. Source: en.wikipedia.org/wiki/Military_engineering

Civil Engineers Those who invent everything other than military warfare Tasks: A Professional Engineer, aka PE, has many sub-disciplines. Define a need or problem Design a solution Build (or manufacture) & Maintain the physical and naturally built environments.

Structural Engineering Analyzes loads and their stresses and forces on the structure.

Mechanical Engineering Emerged as a field during the Industrial Revolution (1750) Applies Principles of Physics and Materials Science Uses Heat and Mechanical Power Analyzes, Designs, Manufactures & Maintains Mechanical Systems

Electrical Engineering Design and Analysis of Electronic Systems Uses electricity, electronics, and electromagnetism Became a profession in the late 19 th century Example of Electrical Engineering Invention: Electronic Telegraph ingeniously solved the need for transmitting communication.

Chemical Engineering Applies physical and life sciences as well as math and economics Converts raw materials into more useful or valuable forms Products developed: food, cosmetics, antibiotics, plastics Used to complete the Human Genome Project

Project: Engineers: Imhotep Archimedes Vitruvius William gilbert Thomas Savery John Smeaton Thomas Edison Leonardo Da Vinci The Wright Brothers Nicolai Tesla Task: Create a short Biography. Map their location Engineer’s Resume Portfolio of engineer’s work with an explanation of at least 3 inventions (1 slide for each invention) If “E” where around today what would they create? Where would they live? Include a bibliography En.wikipedia.org/wiki/Engineering
