Electrification• In June of 1752, Benjamin
Franklin discovered that lightning was indeed an electric current.
• In 1879, Thomas Edison was the first person to harness electricity with the light bulb.
Everyday Uses of Electricity
• Lighting
• Computers
• Television
• Radio
• Automobiles
• Air conditioning/heating
• Refrigeration
Improvements of Economy
• Assembly lines, manufacturing, and producing products would slow down without electricity.
• Cost of maintaining machines is lower than the cost of employing people.
• Machines are quicker and more accurate than humans.
Computers
• The first design of a stored-program computer came in 1945 by john von Neumann.
• Computers have made routine daily tasks and complex tasks continuously easier.
• Since 1945, engineers have continued to develop faster, more powerful and more affordable computers.
Computer Networks
• Computers have been a major contribution to the globalization of economic activities.
• Put together with telecommunications and an informed society, they are a fundamental aid for future economic growth and social development.
Agricultural Advancements
• Traditional Methods– Time consuming
– Horse Drawn Plow
– Planting seeds by hand
– Harvest crops by hand
– 1 farmer fed approx. 2.5
Agricultural Advancements (cont.)
• Conventional Methods– Tractors: The Beginning
• Steam Powered Tractions (1868)
• Gas Powered Tractions (1887)
• Gas Powered Wheel Tractors (1892)
• First Commercial Tractors Sold (1902)
Agricultural Advancements (cont.)
• Conventional Methods (cont.)– Cultivators, Combines,
Mowers
– Increased Production and Efficiency
• 1 farmer can feed 100
– Comfortable• A/C Cabs
• CD Players
Aircraft
• 1903 Wright brothers make first manned and powered flight.
• 1920 Donald Douglas first begins manufacturing aircraft.
• 1994 Boeing creates first aircraft designed by computers.
Airplane Manufacturing IndustryExample: Boeing
2002 Sales (mil.) $54,069
1-Year Sales Growth (7.1%)
2002 Net Income (mil.) $492.0
1-Year Net Income Growth (82.6%)
2002 Employees 166,000
2002 Employee Growth (11.7%)
Air Transportation Industry
• Supplied 1.3 million wage and salary jobs in 2000.
• Economic impact by delta airlines alone in the greater Cincinnati area was $2.075 bill.
The Automobile
• Henry Ford uses the assembly line to revolutionize the auto industry
• Most industry uses the assembly line in some form today
The Automobile (cont.)
• The Automobile itself is a product of many engineers
• Transportation is an essential part of our lives
• Automotive industry provides thousands of jobs
Automotive Effects On Economy
• Economic stability through road ways
• Engineers work to solve emissions problem
• Stimulate economic growth by developing hybrid gas/electric cars, fuel cell powered cars and other alternative fuels
Interstate Highways
• One of our most cherished assets.
• Life savers.
• US highways worth over $4.4 trillion.
• Shaped the nation by allowing easy access through standardized routes to all parts of the nation.
Hathaway Bridge Corridor
• Bay county mainland and Panama City beach
• Design build team awarded $81.5 million
• Contract to design and construct the new bridge
• Project completes in winter 2003
Conclusion
• Engineers play an important role in economical growth and stability.
• Technologically advanced society.
• Developing new tools and machines to simplify work and making people’s life more efficient.
• Makes the economy more prosperous and stable.
