Abstract :
We exist in a world of machines and the technical basis for these machines lies in the steam engine developed during the 1780s by James Watt. The concept of deriving useful mechanical work from new fuel such as wood, coal, oil, and now uranium was revolutionary. Watt also developed the slider-crank mechanism to convert reciprocating motion to circular motion. To improve on this beginning, basic engine, the people who followed Watt created the scientific discipline of thermodynamics and perfected power transmission through gears, cams, shafts, bearings, and mechanical seals. A new vocabulary involving heat, energy, force, and torque was born with the steam locomotive. Nano technology will extend the capabilities of engineers and enable more complex designs to be dispatched anywhere.
