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.
