1 CHAPTER 1 -The History of Engineering ME101 Dr. Nhut Tan Ho

2 Lecture Objectives & Activities Explore definition of Engineering Provide an overview of history of disciplines Active Learning Activities Pair-share discussion: Definition of engineering Small group work: Engineering in an era

3 Pair-share activity Work with a partner to create a definition for “engineering” (be as creative and bold as you can!) Report your definition to the class

4 1.1 Introduction Definition of Engineering The profession in which knowledge of the mathematical and natural sciences, gained by study, experience, and practice, is applied with judgment to develop ways to use, economically, the materials and forces of nature for the benefit of mankind.

5 1.2 Getting Started Prehistoric Culture Our Computer Age The Speed of History Quick Overview

6 1.4 The Overview Approach Engineering the Temples of Greece The Roman Roads and Aqueducts The Great Wall of China

7 1.5 Traveling Through the Ages 1200 B.C. – A.D. 1 Quality of wrought iron is improved Swords are mass produced Siege towers are perfected Greeks develop manufacturing Archimedes introduces mathematics in Greece Concrete is used for arched bridges, roads and aqueducts in Rome.

8 1.5 Traveling Through the Ages: A.D Chinese further develop the study of mathematics Gunpowder is perfected Cotton and silk manufactured

9 1.5 Traveling Through the Ages: Silk and glass industries continue to grow Leonardo Fibinacci, a medieval mathematician, writes the first Western text on algebra

Traveling Through the Ages: First toilet is invented in England Galileo constructs a series of telescopes, with which he observes the rotation about the sun Otto von Guerick first demonstrates the existence of a vacuum Issac Newton constructs first reflecting telescopes Boyle’s Gas Law, stating pressure varies inversely with volume, is first introduced.

Traveling Through the Ages: Industrial Revolution begins in Europe James Watt patents his first steam engine Society of Engineers, a professional engineering society, is formed in London First building made completely of cast iron built in England

Traveling Through the Ages: Machine automation is first introduced in France First railroad locomotive is designed and manufactured Chemical symbols are developed, the same symbols used today (Au, He) Single wire telegraph line is developed

Traveling Through the Ages: Reinforced concrete is first used First synthetic plastic material is created Bessemer develops his process to create stronger steel in mass quantities First oil well drilled in Pennsylvania Typewriter is perfected

Traveling Through the Ages: Telephone is patented in the US by Alexander Graham Bell Thomas Edison invents the light bulb and the phonograph Gasoline engine developed by Gottlieb Daimler Automobile introduced by Karl Benz

Traveling Through the Ages: Wright brothers complete first sustained flight Ford develops first diesel engines in tractors First commercial flight between Paris and London begins Detroit becomes center of auto production industry

Traveling Through the Ages: John Logie Baird invents a primitive form of television The VW Beetle goes into production First atomic bomb is used The transistor is invented

Traveling Through the Ages: Computers first introduced into the market, and are common by 1960 Sputnik I, the first artificial satellite, put into space by USSR First communication satellite—Telstar— is put into space The U.S. completes the first ever moon landing

Traveling Through the Ages: The Concord is first used for supersonic flight between Europe and the U.S. Columbia space shuttle is reused for space travel First artificial heart is successfully implanted

Traveling Through the Ages: 1990-Present Robots travel on Mars The “Chunnel” between England and France is finished GPS is used to predict and report weather conditions, as well as many other consumer applications

The History of the Disciplines Aerospace Eng. Agricultural Eng. Chemical Eng. Civil Eng. Computer Eng. Electrical Eng. Industrial Eng. Mechanical Eng.

History: Aerospace Engineering “Aerospace engineering is concerned with engineering applications in the areas of aeronautics (the science of air flight) and astronautics (the science of space flight).

History: Agricultural Engineering Agricultural engineering focuses on: Soil and water Structures and environment Electrical power and processing Food engineering Power and machinery

History: Chemical Engineering Chemical engineering applies chemistry to industrial processes, such as the manufacture of drugs, cements, paints, lubricants, and the like.

History: Civil Engineering Civil engineering focuses on structural issues, such as: Bridges and Highways Skyscrapers Industrial Plants and Power Plants Shipping Facilities and Railroad Lines Pipelines, Gas Facilities, Canals

History: Computer and Electrical Engineering The world’s business is centered around computers, and their uses are only increasing Electrical is the largest branch of engineering Involved in: Communication Systems Computers and Automatic Controls Power Generation and Transmission Industrial Applications

History: Industrial Engineering Industrial engineers design, install, and improve systems that integrate people, materials, and machines to improve efficiency.

History: Mechanical Engineering Deals with power, the generation of power, and the application of power to a variety of machines, ranging from HVAC to space vehicles.

30 Lecture Recap: Engineering History A continuum: new innovations stand on shoulders of those who’ve gone before Engineers are professionals/leaders Need to understand origin of profession Study history helps understand good qualities of the past, and create new futures
