1. Where did “Engineers” first come from? Engineers where people who “ran” engines and engines came from being ingenious

2. Ingenious  Engine ► Some of the earliest ingenious inventions where war machines, such as this Mangonel. ► This lead to ingenious becoming engine and the war engine.

3. What is an Engineer? (from the dictionary) 1. a person who designs, constructs, and uses engines or machines. 2. a person who manages an engine or locomotive 3. Also someone who creates solutions to problems

7. For the first time, machinery started to become complex in its nature and needing specialized skills to operate. No longer could “anyone” run these machines.

9. Steam Timeline A few of the Highlights 100 A.D. Hero's Engine is Created 1606 Giovanni Battista Della Porta uses steam to make water rise through a column 1690 Denys Papin discovers a way to produce a vacuum using steam but does not pursue the knowledge 1698 Thomas Savery combines the force of steam with the pressure of the atmosphere and patents the first atmospheric engine 1712 Thomas Newcomen produces a self acting atmospheric engine 1769 James Watt is granted a patent for the Separate Condenser Hero’s Steam engine

10. 1780 James Pickard and Matthew Wasborough create an engine with rotary motion by fitting a crank, rod and flywheel to Newcomer's Model 1783 A double acting engine is introduced by Watt - Steam pushes on each side of the piston alternately as opposed to just one side 1786 Boulton and Watt produce a double acting rotative engine 1802 A steam railway locomotive is built at Coalbrookdale, Shropshire Newcomer’s Steam engine

11. 1802 A stern wheel steam paddle tug is created by William Symington 1807 Robert Fulton's ship the "Clermont" becomes the first steamship to provide regular passenger service in America 1825 The First Public Railway to use steam locomotives opens 1827 The era of locomotive success begins in Britain 1838 The Great Western Railway opens 1844 The "Lancashire" boiler is introduced in Manchester by William Fairbairn 1846 The Regulation of Railways (Gauge) Act is passed The "Tank Engine" is born 1850 Randolph Elder fits the first marine compound engine Steam Timeline A few of the Highlights

12. 1865 Commuter Traffic becomes prominent in large cities - Passenger traffic locomotives are introduced by the railways 1878 Willans patents the high speed fully enclosed "inverted vertical" engine 1890 Charles Pain patents the forced-lubrication-high-speed-enclosed engine 1898 The first British express locomotive travels on the Great Northern Railway 1906 Superheating of steam is invented by Dokter Schmidt and used in British Railway locomotives 1938 The streamlined "Pacific" 4-6-2 locomotive "Mallard" reaches a speed of 126 miles per hour (201 kph), This speed still stands as a world record. 1960 The final steam locomotive is built by British Railways - "Evening Star"

13. Steam engines where used for heavy machinery

14. Most steam engines where so large they had to be transported by rail or over water on barges

15. Eventually someone realized you could run a steam engine over land and the first tractors were built

16. 20 HP Oil City Steam Engine 14x17x19”

17. Stanley Steamer Automobile 1897-1924 Invented by the Stanley Brothers from Maine and manufactured in Massachusetts The world’s most popular automobile until about 1908.

18. Every engineering discipline eventually leads to combining different technologies to improve the design

19. Why engineers were important: ► Cost:  Steam engines represented a huge investment that needed to be protected (by taking good care of it)  By protecting people who relied on the engines (try getting stuck in the middle of the ocean with a broken steam engine. Ready to make a call?

20. Why engineers are important ► Their job is to look at how something is done or how something should work and make it happen using principles of engineering and science and mathematics. ► They are often innovators (inventors) ► They find ways of improving the way things work ► They are given challenges to overcome

21. Safety: ► Safety:  Steam engines are operated by super heated water  Water boils at 212 degrees F (100 degrees C) but engines keep their water around 350-400 degrees  If the boiler fails, all the super heated water immediately turns to steam  1 gallon liquid water = 2000 gallons of steam!

22. NYC Steam Explosion NYC Steam Explosion July 2007

23. Other types of engineers: ► Chemical ► Biomedical ► Civil ► Mechanical ► Electrical ► Computer ► Agricultural ► Aerospace ► Aeronautical ► Food ► Communications ► Systems ► Process

24. What do engineers do? ► Engineers create solutions to solve problems ► They identify the problems ► They incorporate new technologies ► They develop plans for making new products/technologies ► They refine what already exists BUILD PROBLEMS DEVELOP IDENTIFY SOLUTIONS IMPLEMENT SOLUTIONS

25. Engineering today ► 1,600,000 engineers in the United States ► 5,000 engineers in Maine ► Engineers are usually very happy in what they do because they get a chance to work on projects that are creative and help people by making something work better or safer.
