James Watt and the Steam Engine
The correct answer is option 'A' because James Watt significantly improved the steam engine, making it a practical and efficient power source during the Industrial Revolution.
Background
- James Watt was a Scottish inventor and mechanical engineer.
- Born in 1736, he is best known for his work on steam engines in the late 18th century.
Improvements to the Steam Engine
- Watt did not invent the steam engine; it was originally developed by Thomas Newcomen in the early 1700s.
- However, Watt made crucial enhancements that transformed it into a more effective machine.
- Key improvements included:
- Separate Condenser: This innovation allowed steam to be condensed outside the cylinder, greatly increasing efficiency.
- Rotary Motion: Watt developed a mechanism to convert the linear motion of the piston into rotary motion, which could power machinery.
Impact on Industry
- Watt's steam engine became a cornerstone of the Industrial Revolution.
- It powered factories, mills, and transportation systems, leading to significant advancements in manufacturing and transportation.
Legacy
- His name is immortalized in the unit of power, the "watt," which is still used today.
- Watt's contributions laid the foundation for modern engineering and mechanization.
In summary, while Watt did not invent the steam engine, his improvements were vital in making it a practical tool that revolutionized industries and transportation.
