THE HISTORY OF STEAM ENGINE
The early development of locomotives and automotive brought the birth of steam engine. The steam engine was thought to be the final solution to the search for a liable motives but it success was never achieved. Though the first steam engine was invented by Thomas Newcomen in 1712 and it was used to pump water. Study shows, that energy is needed for anything to be done.That is why even the early development of locomotives uses coal as it source of energy of which was then the world favorite fuel and it powered anything, even the ill-fated steam planes invented by American scientist Samuel P. Langley. Steam engine In steam engines, the engines takes energy stored in coal and converts it to heat. The heat generated forms the steam which expands the piston cylinder causing the pressure to increase and forcing the piston to rise above atmospheric pressure. The power stroke occurs when cold water is sprayed on the cylinder to lower the temperature which
