Cylinder = a solid geometric figure with straight parallel sides and a circular.
Piston = a disk or short cylinder within a tube in which it moves up and down
Engine = a machine with moving parts that converts power into motion.
constructed = built
Locomotives = a powered rail vehicle used for pulling trains.
The beginning of the steam engine
Because the land travel is slow and difficult. Farmers cannot send their crops to market. Mail and parcels take a long time to receive. Then people started building steam-powered railways and trains.
How the steam engine working?
changes steam energy to mechanical energy.
The water in the cylinder is heated.
Until boiling, the boiling water turns into steam.
The steam expands and then pushes the machine parts.
called piston As the cylinder cools, it creates suction that pulls the piston back down.
Richard Trevithick
who was inventing the first high-pressure steam engine and the first operational steam locomotive
It pulled ten tons of iron and seventy
men on nine miles of track. In just one trip.
Baltimore and Ohio (B&Q).
Horses were pulled on rails with sharp curves. B&Q train owners wanted to try steam, but British trains are too big for railroad tracks.
so Peter Cooper developed and built a small coal-burning steam locomotive called Tom Tum.
James Watt

to spin the wheel It can power many types of machines.
